Secondary Sensor for High Speed Anti-Radiation Missile (HARM)

Experience during the Gulf War demonstrated the need for a secondary sensor for the HARM anti-radar missile. Benefits of adding an appropriate secondary sensor include: mission completion after defense countermesures, increased probability of kill and reduced probability of fratricide. A HARM missile enhancement would be aimpoint select capability from the secondary sensor. A Phase I program is described in which a variety of concepts for secondary sensors will be defined, evaluated, analyzed and subjected to trade-off studies. The output will be a recommeded and preferred ARM/secondary sensor seeker approach for the HARM missile. Epsilon Lambda describes in this proposal a candidate secondary sensor which was delivered to the Air Force in 1992 which is a w-band radar/IR dual mode sensor. This provides the prospect for a tri-mode (ARM/MMW/IR) sensor with attractive and versatile capabilities for all phases of the HARM missile mission. Epsilon Lambda is joined in this proposal by TI, the prime contrator for the HARM missile.
