Adaptive hot clutter mitigation using subbanding

Hot clutter mitigation using an adaptive array is the focus of the paper. A model that includes all relevant hot clutter parameters such as spatial delay, Doppler, and carrier phase angle is developed. Subbanding using DFT or the wavelet transform is implemented prior to adaptive processing and tap delay filtering. A comparison between the two subbanding techniques using the cancellation ratio as a performance measure is presented. The effects of the number of tap delays, jamming angle of arrival, Doppler spread, and jammer relative bandwidth on the performance of an adaptive array are examined.<
