The ojective of this proposal is to develop a multi-frequency and multi-band RF sensor based on the MAP concept and capable of improving the performance affordability for discrimination of ballistic missile threats in complex countermeasure environments. The MAP radar/sensor enhances the detection, identification and location of targets using a priori knowledge of those targets, specifically the target's impulse response, h. The MAP transmitted pulse is the time reversal of the impulse response, h*, or complex conjugate of h, which convolves with the target. MAP differs radically from UWB and Chirp radars in that (1) an arbitrary carrier is used; (2) the TX signal envelope is modulated and bandlimited to the target's frequency response; (3) the duration of the TX signal can be as long as required. A major capability of MAP is the selective enhancement of designated target resonances, or minor resonances, in the presence of both clutter and jamming. At short range, MAP provies up to 24 dB S/N target echo enhancement. The exceeds the performance of chirp (FM) and UWB systems. The present proposal is specifically to design and simulate a MAP RF sensor establishing the effectiveness of target identification in the presence of countermeasures and clutter.
