The disadvantage is that the field anti-jamming test needs to calibrate the power of the track points of the sports car. The traditional method is to manually use the calibration antenna and spectrum analyzer to calibrate and record point by point along the track of the sports car, and then calculate and control the transmission power of the interference source according to the calibration data, which is very efficient. Low, and the calibration data cannot be directly used in the anti-interference test, and it is impossible to automatically adjust the transmission power of the interference source when switching scenes, resulting in a large amount of calculation, long time consumption, and low efficiency

The invention relates to an automatic calibration method and device for satellite navigation outfield anti-interference testing, belonging to the technical field of satellite navigation. It includes a calibration antenna, a spectrum analyzer, and at least two interference sources. It also includes a mobile calibration platform. The calibration antenna, spectrum analyzer and automatic calibration device are all installed on the mobile calibration platform. The automatic calibration device is connected with the calibration antenna and spectrum respectively. instrument connection. The beneficial effect is that it communicates with each interference source in real time through wireless means, obtains the location of the interference source and interference parameters, and combines its own azimuth information and antenna pattern at each calibration point to automatically calculate the interference direction and interference space attenuation, and finally according to The test scenario J / S requires automatic calculation and setting of the interference power of the interference source. It has the advantages of calibrating all interference frequency points at the same time for each trajectory point, and has the advantages of parallel calibration, automatic calculation, high efficiency and time saving.
Description
technical field [0001] The invention relates to an automatic calibration method and device for satellite navigation outfield anti-interference testing, belonging to the technical field of satellite navigation. Background technique [0002] Field anti-jamming test is a common method to test the anti-jamming capability of satellite navigation terminals. The common technique and method is to set up multiple interference sources in the field, and place the satellite navigation terminal on the car for sports car testing. The disadvantage is that the field anti-jamming test needs to calibrate the power of the track points of the sports car. The traditional method is to manually use the calibration antenna and spectrum analyzer to calibrate and record point by point along the track of the sports car, and then calculate and control the transmission power of the interference source according to the calibration data, which is very efficient. Low, and the calibration data cannot be dir...
