Problems solved by technology

[0003] At present, the domestic irradiation command test equipment can only process the irradiation command signal in a specific frequency band and a specific modulation mode. For the irradiation command signal of a specific frequency band, only the corresponding test device can be used. If the irradiation command signal of a different frequency band is received , the test device needs to be replaced to test the irradiation command signal, the function is relatively single, and the versatility is not good

Abstract

The invention discloses a universal irradiation instruction testing system, which comprises a wideband frequency synthesis module, a receiver module, a signal collecting and processing module and a processing module, wherein the first receiving channel of the receiver module receives a first irradiation instruction signal sent from an external antenna in an X waveband; a second receiving channel receives a second irradiation instruction signal sent from the antenna in the X waveband; the wideband frequency synthesis module is used for sending a local oscillation signal to the receiver module;and the signal collecting and processing module responds to a first intermediate frequency signal sent from the first receiving channel and a second intermediate frequency signal sent from the secondreceiving channel, and carries out full-digitalization demodulation on the first intermediate frequency signal and the second intermediate frequency signal. The invention also provides a universal irradiation instruction testing device. By use of the testing system and the testing device, different irradiation instruction signals in the X waveband can be independently tested, the demodulation of the irradiation instruction signals of various modulation ways can be met, and the testing system and the testing device have various functions and exhibit good universality.

Description

technical field [0001] The invention belongs to the design field of irradiation radar test devices, in particular to a general irradiation command test system and a test device. Background technique [0002] Target irradiation radar is a radar used to provide electromagnetic wave irradiation to a designated target, so that the reflected wave of the target can be received and utilized by another sensor. As an important equipment of the air defense weapon system, the target irradiation radar provides irradiation command signals for missiles, and sends target coordinates, speed information and related missile control command information. The irradiation command test equipment can test the correctness of the irradiation command signal, which plays an important role in the daily maintenance, troubleshooting and related use tests of the irradiation radar. [0003] At present, the domestic irradiation command test equipment can only process the irradiation command signal in a spec...
