This proposal addresses the need for advanced signal processing in airborne surveillance and targeting receivers. An innovative real time compressive receiver architecture using surface acoustic wave (saw) transformers is proposed as an adaptive airborne response monitor system. Preliminary investigation indicates the proposed airborne response monitor would be able to provide simultaneous time and frequency domain analyses in real time with 100% probability of intercept. The system would also satisfy size, weight, phase coherency, and programmability requirements. The ability to monitor and process sophisticated signal formats makes the proposed system ideally suited to identification of virtually any type of radar emitter. In Phase I, a design analysis of the proposed response monitor system will address system requirements such as instantaneous bandwidth, resolution, and dynamic range. Simulation studies using design models for critical hardware functions will identify projected performance and simulated actual EW environments.
