Abstract
This paper presents several techniques for mitigating the effects of an inclined linear array on STAP algorithms. A new technique, termed Doppler Warping is shown to completely mitigate the effects of the array inclination on the STAP algorithm by shifting the Doppler filters to track the Doppler frequency variation of clutter over range. After establishing the effects of array inclination on STAP algorithms, several techniques are presented to reduce the array inclination effects. Doppler Warping is shown to be computationally very inexpensive and to completely mitigate the effects of array inclination. Covariance analysis results are presented.
