58 -- RIMS S-BAND UPGRADE SOL N00167-97-R-0044 DUE 072597 POC MaryAnne Golling (301) 227-3301 This is a reissue of a combination synopsis/solicitation that was first published as a small business set-aside. This requirement is being reissued as unrestricted, since there was no response as a result of the first announcement. Naval Surface Warfare Center -- Carderock Division (NSWC,CD) intends to obtain coherent step-chirp radar hardware that will expand existing frequency coverage of the Radar Imaging Measurement System (RIMS), currently owned and operated by NSWC,CD, down to S-band (2-18 GHz total frequency span) and permit fully agile frequency interleaving between frequency bands. The hardware is intended to be a commercial product modified as necessary to meet these requirements. (i) This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; a proposal is being requested and a written solicitation will not be issued. (ii) Solicitation N00167-97-R-0044 is issued as a request for proposal. (iii) The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular 90-46. (iv) The associated standard industrial classification code is 3825. (v) The following product shall be procured through this solicitation: Item 0001 -- coherent step-chirp radar hardware that will expand existing frequency coverage of the Radar Imaging Measurement System (RIMS), currently owned and operated by NSWC,CD, down to S-band (2-18 GHz total frequency span) and permit fully agile frequency interleaving between frequency bands. (vi) The following information shall apply to all hardware/equipment being acquired under this procurement: It is expected that the hardware being procured will replace existing core radar hardware of the RIMS in order to accomplish the specified frequency coverage and frequency interleaving. The hardware must be able to work with and be integrated into the existing RIMS hardware as described in the following specifications. The vendor shall be responsible for the design and manufacture of the radar hardware described herein. Upon demonstration to the government of proper operation of the hardware, the equipment shall be shipped along with all specified documentation. Technical Specifications: Frequency Requirements: Frequency Coverage: Total frequency coverage is to be from 2 GHz to 18 GHz continuous, adjustable under computer control in frequency steps equal to that of the frequency source. System must be capable of expanded frequency coverage (under future modification) of 100 MHz through 100 GHz without degradation of current operation. Frequency Source: The frequency source is a Comstron FS2000B-18 (gov't equipment). The required system must provide computer control of the frequency source to the full resolution of frequency step sizes available, via the standard BCD input of the frequency source unit. Output of the frequency source shall be mixed with a local oscillator in the radar hardware of no less than 1.5 GHz to achieve the output of 2-18 GHz of the system, while maintaining the phase coherency of the frequency source. Frequency Agility: Under computer control, the system must be able to switch frequencies of the current frequency source within 1 microsecond. Frequency Table: As used here, a "chirp" is a sequence of discrete frequency steps beginning at an operator specified start frequency, incremented by an operator specified step size, and comprised of an operator specified number of steps. Each frequency in a "chirp" is transmitted, and a reply received by the system, before a second frequency is transmitted. A frequency table is a collection of "chirps" and specified single frequencies programmed under computer control by the operator. The system must have an agile frequency table permitting interleaving of individual frequency chirps of different major frequency bands (at least 4 bands), interleaving of individual frequencies of frequency chirps of different major frequency bands (at least 4 bands), and interleaving a single frequency between frequencies of multiple frequency chirps (band independent). The frequency table must be capable of a minimum of 8192 individual frequency entries. A step size of zero must be an acceptable value for an individual frequency chirp. The system must provide the operator with the information of how much time it will take to sweep through the frequency table with the current system settings. Frequency Table Triggering: The system must be capable of initiating a frequency table sweep either by internal trigger under computer control, or by an external TTL signal of 1 microsecond duration. Timing Requirements: Pulse Repetition Frequency (PRF): The PRF must be adjustable under computer control from 100 Hz up to 2 Mhz. Transmit Pulse Width: Pulse width must be adjustable under computer control from 5 to 10 nanosec to 100 microseconds. Target Range: Sample range to test target must be adjustable under computer control from a minimum of zero to a maximum of at least 100 nautical miles (600,000 feet). System timing must be able to utilize the theoretical range permitted at each PRF, up to a maximum of 100 nautical miles. System must be capable of sampling targets that are ambiguous in range (further away in time than the next transmit pulse), excluding specific ranges that are restricted due to subsequent transmit pulses. Target Range Offset: System must be able to offset (delay) the point from which zero range is measured to account for variable cable and other delays utilized in different configurations of existing government equipment. (This configuration will be provided to the successful offeror.) This offset (delay) must be variable under computer control, on a per band basis, from zero to a minimum of 6 microseconds in 1 nanosecond increments. Range Gates: System must have a minimum of two range gates, selectable under computer control, for target measurement under all modes of operation. The system must be capable of futureexpansion to a total of 8 range gates. Time spacing between range gates must be under computer control and capable of each being set independently. Range gate spacing must be capable of being set from zero to 20 microseconds. 2.2.6 Range Tracking: System must be capable of manual range tracking of targets. Manual range tracking must have range increments selectable under computer control from a minimum of 10 nanoseconds to a maximum of 5000 nanoseconds or greater, in 10 nanosecond increments. For manual tracking, actual range changes must be performed with a single mouse click (if on the computer screen) or by a single contact of an electrical switch (if utilizing an electrical switch for range changes). System must be expandable (under future modification) to include automatic range tracking utilizing the split gate tracker method. Automatic tracking, when implemented, must be capable of being utilized by first tracking manually and then enabling automatic tracking when the operator is ready. Automatic tracking must also be able to scan a start/stop range and lock on the biggest target in that range. Any range gates needed for automatic range tracking must be in addition to the minimum of two range gates specified for use in making target measurements. Range tracking must also be able to track a target to any of the installed range gates in the system (not just range gate #1). Future implementation of automatic range tracking must not degrade any of the current functions of the system.

System must be capable of adjusting output power, via a programmable attenuator, on a frequency dependent basis. RF Transmit Gating: Transistor-transistor logic (TTL) signals must be provided for gating this RF output signal.

Control bits must be independently changeable on a pulse-to-pulse basis by the system. Receiver Channels: System must have a minimum of one receiver channel. System must be expandable (under future modification) to two receiver channels to enable simultaneous co-polarized and cross-polarized data collection with no degradation of existing data collection capability.
