Interferometer Direction Finding of Noise FM Signal Based on Channelized

摘要

According to phase fuzzy when interferometer direction finding leading to the problem of low accuracy, put forward a approach to direction finding of the noise FM signal which based on channelized. Use interferometer direction finding of narrowband signal to solve the direction finding problem which is noise FM signal of broadband through the channelized, and the process can improve the accuracy of direction finding. Then improve the method of interferometer direction finding, that is to use the method of double frequency defuzzication, solve the problem of the baseline length of the interferometer, make the baseline length independent with center frequency, and remove the phase fuzzy. The simulation shows that the method is true and effective.
