A Clutter Suppression Method Based on Angle-Doppler Compensation for Airborne Radar with Uniform Circular Arrays Antennas

摘要：

The clutter distribution of airborne radar with uniform circular array antennas varies with ranges and received data in different range gates are not independent identically distributed vectors, so the statistical STAP methods degrade. In this paper. based on the detailed analysis of clutter distribution for airborne radar with uniform circular array antennas, the conclusion that the non-linear relation between space angle and num ber of arrays results in the nohom ogeneity at range for airborne radar with circular array antennas is gained. A clutter suppression method for airborne radar with uniform circular array antennas is proposed in this paper. This method involves in a preprocessing with MADC method to align the centers of cjutter spectrum in different range gates and subsequently clutter suppression in other azimuths with DBU technology. Simulation results show the validity of this method.
