The objective of this task is to develop radar transmit waveform strategies, and their associated receive processing methods, for single and multi-mode operations for monostatic and multi-static radar applications. The waveforms should exploit the potential degrees of freedom (DOF) on the platform(s) and consider the electromagnetic environment with which they interact. The goal is to improve air and ground moving target indication (AMTI, GMTI) and imaging by adjusting the transmit waveform using spatial, temporal, frequency and polarization diversity in the radar transmitter and across available distributed sensors. Feedback from the receive platform(s) should also be considered to adjust the waveform(s) for the next pulse repetition interval. A waveform optimization process must be developed to determine what waveform is transmitted so that it exploits its expected electromagnetic interaction with the surrounding clutter, i.e. multi-path scattering. Illumination from one to multiple sensors, either cooperatively or non-cooperatively, should be considered. The sensors would be potentially distributed therefore yielding a geometrically diverse aspect, however spatial diversity on a single platform should also be exploited, i.e. independent control of a phased array?s sub-apertures. Also to be considered are the use of multiple receive platforms that can operate either passively or actively. Coherent processing is essential and techniques of coherently combining multiple receive sensors signals for improved mission performance must be developed. Multi-mode operation from a distributed collection of sensors (multi-statics) is also of interest for simultaneous combinations of AMTI, GMTI, and synthetic aperture radar (SAR) modes.
