Method for testing amplitude and phase response of antenna array receiver through non-circular signals

The invention discloses a method for testing an amplitude and phase response of an antenna array receiver through non-circular signals. According to the method, the problem of an amplitude-phase response error in an antenna array signal receiving model applied to the antenna array signal processing algorithm in practical application is solved. Under the situation that two or more non-circular signals with the known direction and signals with the unknown direction exist at the same time, the non-circular signals are used as a correction source. The amplitude and phase response of an antenna array is estimated through the orthogonality relation between a sub noise space of a sample self-correlation matrix of an extension vector of a signal receiving vector of the antenna array and an extension direction vector of the non-circular signals, and therefore accurate estimation of the receiver amplitude and phase response is provided for the antenna array signal receiving model used for antenna array signal processin
