Direction-of-arrival and polarization estimation based on sparse sensing

This paper discusses how to acquire an estimation of DOA(Direction of Arrival) and polarimetric parameters of arriving sources with high accuracy, for polarimetric array is seldom used till now, and even when it is used, it is still hard to acquire an estimation with high accuracy. We apply CS-based method instead of traditional methods to find solutions for the mathematical model of polarimetric arrays, and we also propose an improvement to it. Finally, we use simulations to verify that CS-based method and our improvement are really useful and the accuracy is high, and practical applications are also discussed.
