Abstract

The invention provides a double-waveband microwave signal detection device, which comprises a first waveband band-pass filter, a second waveband band-pass filter, a first waveband numerical control attenuator, a second waveband numerical control attenuator, a signal detection unit and a real-time control unit, wherein the first waveband numerical control attenuator is connected with the first waveband band-pass filter; the second waveband numerical control attenuator is connected with the second waveband band-pass filter; the signal detection unit is used for carrying out wave detection to obtain a modulation signal from an attenuated input signal; and the real-time control unit is connected with the signal detection unit and is used for controlling the signal detection unit to be selectively connected with the first waveband numerical control attenuator or the second waveband numerical control attenuator and carrying out frequency measurement and output on the modulation signal obtained by wave detection. By use of the technical scheme of the invention, the technical problem of low detection efficiency of the microwave signal detection device in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of radio testing, in particular to a dual-band microwave signal detection device. Background technique [0002] The pulse system radar generally transmits and receives pulse modulation signals, and the signal band varies with the radar frequency band, and the signal power span is relatively large. For the pulse system radar, in the test process, it is often necessary to judge whether the received signal contains the pulse modulation signal of the target frequency band, or judge whether there is a strong radiation leakage signal in the space. However, in the prior art, commonly used microwave signal detection devices can only detect microwave signals in one band, and this method is relatively inefficient. Contents of the invention [0003] The invention provides a dual-band microwave signal detection device, which can solve the technical problem of low detection efficiency of the microwave signal detection...
