Abstract :
This paper evaluates the performance of partial adaptive space-time adaptive processing (STAP) approaches based on Doppler prefiltering for inclined sideways looking array (ISLA) airborne radar, in which the angle between the axis of a linear antenna array with that of platform flight is not zero. In ISLA the STAP is more complex than that in a sideways looking array (SLA), which is the particular case that these two axes are identical. After analyzing the characteristics of the clutter spectrum in ISLA, the principle of reduced rank STAP based on prefiltering is proposed and discussed. Also, several computer simulations are presented
