However, this method needs to perform frequency domain anti-interference on multiple channels of the array antenna, and then perform space-time domain processing. Therefore, the implementation complexity is high and the calculation resource consumption is large, which makes the application on the satellite have great limitations.

The invention relates to a method for processing satellite communication signals, which comprises the steps of estimating or determining the direction of a signal to be received; scanning within a certain angle range by taking the direction as a center to estimate a spatial frequency spectrum of the signal; determining the maximum value of the spatial frequency spectrum; comparing the maximum value with a threshold; and carrying out space-time domain anti-interference processing on the signal in the case that the maximum value is less than the threshold. In addition, the invention further relates to a system for processing the satellite communication signals. According to the method or system, the implementation complexity can be significantly reduced, and the consumption of computing resources is reduced, thereby being more suitable for the application on satellites with limited resources.
Description
technical field [0001] The present invention generally relates to the field of satellite communication, and in particular, relates to a method for processing satellite communication signals. Furthermore, the invention relates to a system for processing satellite communication signals with integrated anti-interference capability. Background technique [0002] In satellite communications, the uplink is more vulnerable than the downlink, because the uplink is usually more likely to be interfered, which makes the research on the spaceborne anti-jamming technology for the uplink particularly important. For low-orbit satellite communication systems, due to the long communication distance, low satellite orbit and fast relative ground motion, the communication link has low signal-to-noise ratio at the receiving end, significant Doppler effect, and limited communication time. features. At the same time, during the movement of the satellite, the direction of the signal will change r...
