Application Research of Radar Testability Optimization Method

摘要:

基于雷达等电子产品测试性要求的不断提高,对产品进行测试性设计迭代并进行测试性验证,成为对电子产品的普遍要求。由于初始设计有缺陷、覆盖故障模式不全等引起测试性设计不能满足要求,开展闭环测试、脉冲检测、隔离策略优化等测试性改进,最终选择软、硬件改进相平衡的方案,通过回归试验,获得满足指标要求的检测率和隔离率结果,优化方法促进了产品的测试性设计改进和增长。

Abstract:

With the fast development of the testability demands of electronic products based on radars, the design iteration and testability Validation have already become one of the most fundamental requirements for electronic products. Because the initial design is defective and the failure modes are not covered completely, the test design cannot meet the requirements. Some design measures have been adopted,such as closed loop test, pulse detection, isolation strategy optimization etc. Lastly, a proper scheme is raised by taking the costs of software and hardware into account. The famous fault detection rate and fault isolation rate are obtained through the secondly testability Validation Test. The results show that the optimizations promote the design of the product testability and the improvement measures are effective.
