Research on joint DOA and polarization estimation for alternate polarization array
Huijing Dou, Guo Caihuan, Fengju Chen, Qianlong Wang · 2014
For polarization sensitive array (PSA) is limited by many restrictions in engineering applications, we studies a new alternate polarization array (APA). Analysis its performance of joint spectrum estimation of polarizational and spatial domain, and compared with the PSA. Study shows that compared with the PSA, the joint spectrum estimation of polarizational and spatial domain performance of APA approaches that of PSA, but the equipments and the number of channel is cut by half. APA overcomes the problems caused by the complexity of the PSA system, so it has a wide application prospect in the field of array radar.
