Abstract

The invention discloses a lightning electromagnetic pulse damage effect judgment method for an airborne very-high-frequency communication radio station. The lightning electromagnetic pulse damage effect judgment method comprises the steps of: firstly, establishing a test platform; secondly, determining lightning electromagnetic pulse waveform types and single waveforms and amplitudes contained inthe lightning electromagnetic pulse waveform types; thirdly, detecting sensitivity performance parameters before testing, and recording parameter values; and finally, respectively carrying out a pin injection test and a cable induction test, comparing the obtained sensitivity performance parameter value after the test with the sensitivity performance parameter value before the test so as to determine whether a lightning electromagnetic pulse damage effect occurs. The lightning electromagnetic pulse damage effect judgment method is simple, reasonable and effective, can improve the judgment accuracy rate based on the actual application requirements, can effectively judge whether the airborne very-high-frequency communication radio station has the lightning electromagnetic pulse damage effector not, and further can accurately judge the lightning induction transient sensitivity level of the tested equipment.

Description

technical field [0001] The invention belongs to the technical field of lightning damage testing of airborne equipment, in particular to a method for measuring the damage effect of an airborne VHF communication station under the action of lightning electromagnetic pulses. Background technique [0002] The lightning environment is an electromagnetic environment that poses a great threat to airborne electronic equipment. The lightning electromagnetic pulse (LEMP) has the characteristics of high power, wide frequency bandwidth, and short duration, and it is very easy to couple into the electronic equipment to cause interference and damage. effect. Therefore, usually airborne electronic equipment needs to conduct lightning induction transient sensitivity test to determine its sensitivity to lightning electromagnetic pulse. At present, the standards related to lightning induction transient sensitivity test include RTCA / DO-160G, SAE ARP5412, MIL-STD-461G (cs117), AECTP-250 and GJB...
