Abstract:
In view of the unknown and the time-varying clutter environment,the target recognition is discussed in a known state of target polarization.For the receiving system with two polarization orthogonal channels,two signals are weighted by complex number and compared with the anticipated signal in order to make the means quare error a minimum by use of polarization adaptation.The interference is inhibited and the target signal is enhanced.For the cases that the clutter polarization state is steady and varying,the effects are simulated and the result validates the algorithm.The step factor range of the algorithm is discussed.The target polarization characteristics is extracted and the target recognition is performed.The recognition recursive algorithm is proposed.The recognition result is simulated and the result validates the method.
