Abstract
Space-time adaptive processing is a useful technique for clutter mitigation in airborne radars.
space-time adaptive processing algorithms usually require estimation of interference covariance
matrix with limited training data and high complexity in processing. To overcome these
problems, in this paper, deterministic clutter subspace and the direct data domain method are
introduced. Two methods are presented. In the first proposed method, filter coefficients are
calculated by estimating airborne radar parameters and also calculation of interference
covariance matrix. The sensitivity of estimated parameters is also computed. By extending
clutter subspace, the suggested method could get more robust against parameter estimation. In
the other proposed method, the direct data domain is employed for calculating the coefficients
vector by reducing the size of filters. Finally, the performance of the suggested algorithms is
improved by utilizing other methods such as using more taps and deterministic clutter subspace.
