A new method for classification, identification and discrimination of warhead versus decoy based on combined transmit waveforms and radar receiver design is proposed as part of the Phase-I effort. Fully geared for software implementation, this new methodology is based on jointly optimizing transmit waveform and receiver filter for automatic target recognition and identification of multiple targets. The proposed technique is applied and illustrated for a three as well as a four target problem. The resulting probability of correct classification is significantly better than that achieved by a conventional chirp or any other waveform. As part of the Phase-I effort an implementable prototype MATLAB package for missile identification and better classification using the proposed approach for MDA personal use will be developed and delivered. The transmitter-receiver waveform pairs proposed here are optimal in the sense that 'no other' pair generates a greater target separation in the received signal subspace for better target classification. Phase I efforts will concentrate on quantifying the improvement in performance by the proposed methods and will be supported by analytical study as well as simulation results. A wide range of wireless communication systems may benefit from optimal trans-receiver design, including high-mobility cellular systems, low-mobility short-range systems, wireless local loop applications, satellite communications, and wireless LAN. By employing the optimal trans-receiver design along with an array of sensors, it is possible to multiplex channels in the spatial dimension just as in the frequency and time dimensions. The optimal trans-receiver design technology proposed here can significantly improve wireless system performance and economics for a range of potential users. It enables operators of PCS, cellular, and wireless local loop (WLL) networks to realize significant increases in signal quality, capacity, and coverage. Operators often require different combinations of these advantages at different times. As a result, those systems offering the most flexibility in terms of configuration and upgradeability are often the most cost-effective long-term solutions. The flexibility of optimal Tx-Rx technology allows for the creation of new value-added products and services that give operators a significant competitive advantage.
