“…With the development of radar solid-state, most existing radars adopt PIN limiters for protection [3] . In the research on existing PIN limiters, the tolerance threshold and nonlinear performance of PIN limiter [4] are mainly studied from the aspects of PIN diode modeling and heating simulation [5][6][7] , PIN diode DC voltage injection [8] and PIN limiter RF injection [9,10] , etc., but few studies have been conducted on the radar receiving front end in combination with limiter and low noise amplifier. In this paper, the RF injection test is conducted on the radar receiving front-end system, the tolerance threshold is measured, the relationship between the damage of the receiving front-end and the injected signal power, pulse width, duration, and other factors is studied, and the influence of high-power microwave weapons on radar at different distances is analyzed, which can provide theoretical support for the RF front-end protection design of radar.…”

In order to study the tolerance threshold and damage process of radar receiving front end against high power microwave pulse attack, the relationship between the damage of receiving front end and injected signal power, pulse width, and duration was obtained by injection test. The experimental results show that the damage of PIN limiter by high power microwave is a slow worsening process near the damage threshold. Based on the test results, the radar withstanding range of high-power microwave weapon attack is calculated theoretically, which can provide theoretical support for the radar receiving front-end design.
