Embodiment 1

[0033] This embodiment is a process of verifying the reliability of a radar microwave product by using a reliability test verification system for radar microwave products provided by the present invention.

[0034] The cold soak temperature of a radar product is -55°C; the hot soak temperature is +70°C, and the ground working temperature in hot weather is +70°C; the maximum heating rate is 11.5°C / min, and the maximum cooling rate is 12.3°C / min. The duration of one cycle is 8h. Only in the hot days of the cycle, the ground does not work and enter moisture during the working stage, and keep the dew point temperature ≥ 31 ° C. In other stages of the test cycle, do not inject moisture, do not control the humidity, and the air in the test chamber should not be dried . There is one vibration period and four vibration magnitudes in the cold weather and hot weather phases of the entire profile. Vibration stress values, such as acceleration power spectral density, stress application ...

Abstract

The invention discloses a reliability test verification system applied to a radar microwave product. According to the system, a temperature and humidity stress test subsystem and a vibration stress test subsystem are organically connected with a microwave anechoic chamber, a combined environment test capable of simulating temperature, humidity, vibration and other stress is set up, the problem that reliability verification of the product is insufficient because an existing test system cannot comprehensively test function and performance indexes of the radar microwave product is solved, a testverification means is provided for increasing the reliability level of the radar microwave product and meeting the new requirement of approaching practical examination, therefore, the development cycle of the product is shortened, and the system has huge economic benefit.

Description

technical field [0001] The invention belongs to the technical field of reliability test verification of radar microwave products, and in particular relates to a reliability test verification system for radar microwave products. Background technique [0002] At present, the reliability test of radar microwave products is a comprehensive environmental test that places radar microwave products in a comprehensive test box that simulates the actual storage and working environment, and applies temperature, humidity, and vibration compound stress. However, the difference between radar microwave products and other electronic equipment reliability tests is that the performance of transmitting and receiving needs to be tested through space radiation. Due to the high power of microwaves emitted by radar microwave products, if no protective measures for absorbing microwaves are taken, the microwaves reflected from a short distance will damage the radar. [0003] In the past, when condu...
