Description

For Warning Receiver Upgrade Program 1. Who makes the APR-39? Answer: Northrop Grumman. 2. Generally, how does the APR-39(V)1 work? Answer: Antennas receive radar signals from systems, which is in turn transmitted to a threat display in the cockpit. Enhances situational awareness and increases survivability by threat system avoidance. From Journal of Electronic Warfare, JUNE 2000 : Radar Warning Receivers: The Digital Revolution by Dave Adamy "An RWR is a specialized receiving system used to identify, locate and display threat radar signals very quickly. Although mostly associated with aircraft, RWRs also protect ships and ground-mobile assets. The RWR typically has an instantaneous 360? field of view and covers the whole radar-threat spectrum quickly enough to receive the first beam of a radar signal to reach the protected platform. Its processing only identifies known threat signals from a threat-parameter-identification table. It is optimized for rapid data throughput, collecting only enough data and performing only enough processing to identify the threat type unambiguously. It typically has enough sensitivity to receive main-beam transmissions and enough angle-of-arrival accuracy to support situational awareness in a cockpit and to hand off threats to a jammer. The RWR must have a 100- percent probability of intercept (POI), or very nearly 100-percent POI, for all threat-signal types it is expected to encounter. POI in this case means the ability to receive and display a signal within a very short time (typically about one second) starting when the first energy (above the sensitivity threshold) from that signal reaches the location of the protected platform." 3. How long has the APR-39 been in service? Answer: 20+years? 4. How many are in the MH fleet? Answer: Not for public information. 5. Why are new or upgraded systems required? Answer: Advancement and proliferation of threat systems has continued unabated. False alarms and lack of fidelity of current system seriously degrades it's usefulness. Confidence in the system is very low. 6. When will the winner be selected? Answer: FY02 7. When will the contract be awarded? Answer: FY02 8. What is the total value of the program? Answer: Depends on estimates we get from interested vendors. POC Jacki Alford (757) 878-5223 x352 or e-mail at jalford@tapo.eustis.army.mil
