Accurate attitude measurement on the electronic reconnaissance aircraft, ship and other platform is the necessary prerequisite for electronic reconnaissance tasks. The traditional method depends on the inertial navigation or GNSS attitude instrument with multi antennas. In addition, for platforms with the electronic reconnaissance and DF (Direction Finding) equipment, their DF capability can be fully utilized. Through the phase difference measurement among signals in interferometer channels based on codeless phase discrimination in frequency domain, combined with the positioning and velocity measurement results from the single antenna satellite navigation receiver, and using the Doppler frequency shift difference of each navigation signal to realize signal separation and direction matching, three attitude parameters of the platform, such as heading, pitch and roll angle can be measured. Finally, the correctness and effectiveness of this method are verified by the analysis and processing on the actual signal from the electronic reconnaissance receiver. This method makes full use of the functionality of the existing hardware platform. It does not add new hardware modules, and only needs to be upgraded in the software. So it explores a new way for the attitude measurement on the electronic reconnaissance platform.
