Interferometry measurement technology is an important method for obtaining high precision navigation information in deep space exploration. This paper describes the principle of connected interferometry measurement and the signal processing method using bandwidth synthesis technology which is utilized for accurately extracting delay related to spacecraft angle location information. Meanwhile, a connected...
To solve the problems in modulation recognition of time-frequency overlapped two-signal in the single-channel, an algorithm based on cyclic cumulants used modulation recognition is presented. Through computing the fourth-order cyclic cumulants of pretreated band signals, the feature vector for classification was extracted, and then use the minimum-error criterion to classify time-frequency overlapped...
