Abstract:
Downward-looking MIMO array 3-D synthetic aperture radar is a hot research recently, it overcomes the layover and can acquire more information with the affordable antenna elements. The multiple transmitters and receivers provide a larger degree of freedom, which could be uesd to reduce the pulse repeat frequency, extend the wide-swath or suppress the interferers and so on. However, there are little literates considering the polarization in this new radar system, this paper introduce the polarization in and proposed a Tikhonov regularization algorithm to reconstruct the 3-D images. The simulation results show the proposed algorithm is excel to FFT method with the SNR increase.
