Automatic test system for active radar interference device

Abstract

The invention discloses an automatic test system for an active radar interference device. The system comprises a main control module, an acquisition module, a communication module, a microwave signalsource, a spectrum analyzer, a microwave power meter, an oscilloscope, a transmitting antenna and a receiving antenna, wherein the main control module, functional modules, test instruments and an active radar interference device to be tested are connected in a specific mode, and the functional modules and the test instruments are controlled through corresponding control instructions of the main control module, so that the main control module simultaneously acquires a working voltage and current parameters of the active radar interference device to be tested, which are collected by the acquisition module, and the communication module acquires state information of the active radar interference device to be tested, frequency domain features of a radiation signal of the active radar interference device to be tested, which are acquired by the spectrum analyzer, time domain features of the radiation signal of the active radar interference device to be tested, which are acquired by the oscilloscope, and the intensity of the radiation signal of the active radar interference device to be tested, which is acquired by the microwave power meter, so that test indexes of the active radar interference device to be tested can be automatically tested.

Description

technical field [0001] The invention belongs to the field of active radar jamming, and in particular relates to an automatic test system for an active radar jamming device. Background technique [0002] Radar jamming device is a jamming device that uses electronic methods to cover up real targets and create false targets to destroy the normal operation of the opponent's radar. It is generally divided into two types: active jamming equipment and passive jamming equipment. Active jamming is usually called active jamming, which refers to the jamming that uses a special transmitter on the operating frequency of the enemy's radar. Passive jamming is also called passive jamming, which uses reflective objects dropped (the most commonly used is metal chaff) interference with radar [0003] Active radar jamming device is a device that generates, amplifies or forwards radar jamming signals, which can be used for active electronic jamming of enemy radars, making it difficult to captu...

Problems solved by technology

However, at present, the main method used in the interference device test is still to manually connect the system before each test, manually set the instrument, and then manually read and record the measurement data during the test. Manual calculation and interpretation are required in the later stage. For frequency band product testing, it is necessary to replace instruments, antennas, and dark boxes. Therefore, there are shortcomings such as complicated connection of test equipment, cumbersome operation, and poor consistency of multiple test data.
