Problems solved by technology

The test method adopted by the anti-jamming receiver is relatively simple. Generally, the satellite navigation signal adopts a single-channel signal output form, and the interference signal adopts a static interference simulation method, so as to realize the anti-jamming receiver test in a microwave anechoic chamber, but for the satellite navigation receiver anti-jamming There is no unified reference standard for capability testing and evaluation, and there is no good reference significance for the stages of receiver testing, finalization and detection

Description

technical field [0001] The invention relates to the field of satellite navigation, in particular to a simulation anti-jamming test method for a satellite navigation receiver. Background technique [0002] The test research of anti-jamming receiver has become an important content of satellite navigation development research. At present, various types of satellite navigation receivers are constantly emerging, and their anti-jamming capabilities are also different. The test method adopted by the anti-jamming receiver is relatively simple. Generally, the satellite navigation signal adopts a single-channel signal output form, and the interference signal adopts a static interference simulation method, so as to realize the test of the anti-jamming receiver in a microwave anechoic chamber, but for the satellite navigation receiver anti-jamming There is no unified reference standard for capability testing and evaluation, and there is no good reference significance for the stages of ...
