Study on Electromagnetic Sensitivity of Ku-band Stepped Frequency Radar

In order to improve the combat capability of radar equipment in the battlefield electromagnetic environment, taking a certain type of stepped frequency radar as the test object, and the continuous wave electromagnetic radiation test is carried out by using all-level irradiation method to reveal the law of continuous wave electromagnetic radiation effect of radar equipment. The results show that the peak level of target echo is suppressed under different interference frequencies. In view of the shortage of research on electromagnetic radiation sensitivity of radar equipment, the electromagnetic sensitivity test is carried out to determine the sensitivity criterion of radar equipment, which lays a good foundation for exploring radar equipment's battlefield survivability.
