Navigation deception jamming detection method based on pseudo-range variation of single receiver

The invention provides a navigation deception jamming detection method based on pseudo-range variation of a single receiver, which comprises the following steps of: firstly, calculating a predicted value of the pseudo-range variation through ephemeris information and positioning information, and then calculating an observed value of the pseudo-range variation through a pseudo-range observed value; and finally, the deception jamming detection is realized by comparing the consistency of the observed value and the predicted value of the pseudo-range variation, so that the deception jamming detection method can effectively realize the detection of deception signals of which the coming directions are different from the coming directions of real signals, does not limit the deception signals from the same direction, has more excellent detection performance, and greatly improves the accuracy of deception detection. 本发明提供一种基于单接收机伪距变化量的导航欺骗式干扰检测方法，首先通过星历信息、定位信息计算伪距变化量的预测值，再通过伪距观测值计算伪距变化量的观测值，最后通过对比伪距变化量观测值和预测值的一致性实现欺骗干
