Abstract : Described is a dual frequency moving target radar system having a lower frequency channel which provides relatively good moving target detection in the presence of such obstacles as foliage and precipitation and a higher frequency channel which provides accurate location of targets wherein the Doppler signals from the two channels are correlated to provide suitable target identification which target and clutter are present in the same resolution cell. The Doppler frequency is processed to distinguish the moving target from other returns. Electroacoustic transducers can be used in either of said channels to aid in target identification. (Author)
