Abstract

Abstract:
The two-dimensional filtering approach often referred to as space-time processing, (STP) has
been the subject of considerable research interest over the past two decades. The space-time
processing (STP) is a crucial technique for the new generation airborne radar with high air-toground
performance. Slowly moving ground targets produce a reflected signals which could
not be distinguish from the surrounding clutter reflections, The results in either space
processing, (adaptive array) or temporal processing, (MTI) will be miss detection of the
desired target which has Doppler frequency and angle of arrival near to that ones of the
clutter. Moreover ground based jammers could produce a wide frequency spread jamming
signal with relatively high power to confuse airborne radars. However STP could significantly
reduces the effects of both the clutter and jammers.
