Embodiment 1
[0043] A method for accurately testing MSK decoding sensitivity applied to an interrogator, characterized in that it includes:
[0044] S1: Determine the test equipment.
[0045] In the above steps, the test equipment includes a response simulator, a circulator, a variable attenuator, a fixed attenuator, a peak power meter and a network analyzer.
[0046] In the MSK working mode, the interrogation signal of the interrogator is encrypted, and the code changes all the time, and the response signal must also change accordingly to decode, but the analog response signal compiled by the general instrument cannot change accordingly, so only a special test instrument can be selected - Response simulator to test the interrogator's MSK decoding sensitivity parameters.
[0047] All interrogators have Σ and Ω radio frequency channels, of which the Σ channel is the main inquiry receiving channel, and the Ω channel is used for sidelobe suppression; the response simulator is a single radio fr...
