Rotary single antenna-based deception jamming detection method

The invention provides a deception jamming detection method based on a rotating single antenna, which comprises the following steps of: firstly, calculating an estimated value of a signal arrival azimuth angle through signal information and rotating single antenna parameters, and then obtaining a theoretical value of a real signal arrival azimuth angle through ephemeris information; and finally, deception jamming detection is realized through the consistency of the estimated value and the theoretical value of the arrival azimuth angle difference of the paired signals, so that the method can effectively realize detection of deception signals in different directions from real signals, does not limit the deception signals from the same direction, has more excellent detection performance, and is suitable for popularization and application. The spoofing detection accuracy is greatly improved; meanwhile, a residual sum of squares method is adopted to reduce the negative influence of measurement errors, equivalently
