Abstract

Abstract:

Because in the unknown complex battlefield environment, there may be multiple illuminators around the receiver, the basic information on the illuminator is unknown, and it is impossible to distinguish between interested and interfering signals, so that it is impossible to obtain accurate direction information on the interested station, we propose a cyclostianarity-based direction of arrival estimation method. First, for unknown cyclostiaonarity in the passive bistatic radar, we propose to use the cyclic autocorrelation function of the received signal to obtain cycle-frequency information on each base station signals. Then the cyclostianarity of the signal of interest is applied to enhance the signal of interest, while suppressing other clutters. Finally, the simulation method verifies that the proposed method can obtain more accurate direction estimation than the conventional method, and that it is also applicable to the underdetermined case where the number of antennas is less than the number of sources.

Key words: passive bistatic radar, cognitive radar, frequency offset, direct signal reconstruction, target detection, cyclostationarity
