Abstract

The present application provides a detection method and device for synthetic aperture radar. Wherein, the method includes: receiving the target SAR transmission signal; analyzing the target SAR transmission signal to obtain the signal parameter set of the target SAR transmission signal; according to the signal parameter set, calculating the threat of the target SAR coefficient; according to the calculation result of the threat coefficient, match with the SAR threat level comparison table to determine the threat level of the target synthetic aperture radar; wherein, the signal parameter set includes at least the bandwidth and pulse repetition frequency of the target synthetic aperture radar emission signal . In this way, the amount of calculation in the SAR threat assessment process can be reduced, so that when the SAR is detected, the threat level of the target SAR can be determined more quickly, and the detection efficiency of the SAR is improved.

Description

technical field [0001] The present application relates to the technical field of anti-reconnaissance protection, in particular to a detection method and device for synthetic aperture radar. Background technique [0002] Synthetic Aperture Radar (SAR for short) is an advanced earth observation sensor that can generate high-resolution images of fixed targets on the ground and precisely locate the targets, thereby achieving the purpose of classifying, identifying and locating ground targets and then attacking them. In electronic warfare or anti-reconnaissance, SAR threat assessment can be performed based on hierarchical indicators. [0003] In the process of realizing the prior art, the inventors found that: [0004] SAR threat assessment through hierarchical indicators requires a large computational workload. Moreover, for the reconnaissance target, different platforms carried by SAR have different threat levels. Correspondingly, the anti-reconnaissance protection measures ...
