Adaptive Sidelobe Clutter Cancellation System.
Abstract
The patent application relates to an improved system and technique for increasing interference and clutter cancellation in a signal receiving system. A receiving antenna array is coupled to a plurality of hybrid circuits to provide a sum and all possible difference signals. The sum output is used as a main signal input to a plurality of adaptive canceller loops, while each of the difference outputs are coupled as independent auxiliary signals to one of the adaptive loops to cancel sidelobe interference. The output from the adaptive loops is then coupled to a signal Moving Target Indicator (MTI) and Fast Fourier Transform Filter (FFTF) to cancel clutter from the main lobe.
