Automatic test system of airborne receiver

Abstract

The invention relates to an automatic test system of an airborne receiver. The system is composed of a zero-slot controller, a switch, a processing device, a test rack, and a communication and pulser unit. The zero-slot controller is used for sending a direct-current power supply command and a microwave excitation signal command to the switch and also sending a communication and pulse command to the communication and pulser unit. The switch is used for forwarding the commands to the processing device. The processing device is used for parsing the direct-current power supply command and the microwave excitation signal command and outputting a direct current and signal to the test rack. The communication and pulser unit is used for parsing the communication and pulse command and outputting a communication and pulse signal to the test rack. And the test rack transfers the signals to an airborne receiver. With the zero-slot controller, testing programs can be loaded, so that full-automatic testing of multi-channel multi-frequency-point testing projects can be realized; and the test data are stored automatically, so that the test efficiency can be improved. Network controlling and test data reading are realized by a network server.

Description

technical field [0001] The invention belongs to the field of airborne radar equipment, in particular to an airborne receiver automatic test system. Background technique [0002] Airborne receiver is an important part of airborne radar equipment, and its performance parameters and indicators directly affect the combat effectiveness of the entire radar. When mass-producing receivers, multiple indicators such as frequency, power, noise figure, phase noise, channel isolation, and image rejection of multiple channels of the receiver need to be tested to verify and evaluate the function and performance of the receiver index. [0003] At present, the system for testing airborne receivers usually includes: general-purpose test instruments (including microwave signal sources, spectrum analyzers), test racks, and DC power supplies, but the personnel who test airborne receivers need to manually test the Spot checks are performed at several frequency points, which not only requires re...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in the prior art, the personnel who test the airborne receiver need to use a manual test method to conduct spot checks on several frequency points of a certain channel, which not only requires repeated plugging and unplugging of cables, but also cannot automatically Record data, resulting in low test coverage and low test efficiency
