Embodiment Construction

[0117] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0118] The existing radar emitter signal evaluation methods have one-sided evaluation angles, insufficient evaluation systems, and evaluation methods that are either too subjective or lack of subjective or improper subjective and objective fusion methods, and their practicability is poor. The present invention can reasonably and effectively realize various intrapulse feature evaluations of radar emitter signals based on actual environments, and scientific and effective evaluation helps to select features that can highlight radar emitter signals, so as to facilitate subsequent radar emitter signals sorting and identification...

Abstract

The invention belongs to the technical field of radar radiation source signal characteristic evaluation in electronic countermeasure, and discloses a radar radiation source signal intra-pulse characteristic comprehensive evaluation method and system. The method comprises the following steps of firstly, carrying out feature extraction on a received radar radiation source signal, and carrying out feature evaluation index measurement and normalization according to an established evaluation system; carrying out improved interval analytic hierarchy process by combining expert priori knowledge and an actual environment, and establishing a nonlinear equation optimization model by using an improved projection pursuit algorithm; and finally, performing final subjective and objective decision fusionby using a projection spectrum gradient algorithm. The radar radiation source signal intra-pulse characteristic evaluation method and system can reasonably and effectively realize various radar radiation source signal intra-pulse characteristic evaluations based on an actual environment, and scientific and effective evaluation is carried out to help to select characteristics capable of highlighting radar radiation source signals so as to facilitate the subsequent radar radiation source signal sorting and identification.

Description

technical field [0001] The invention belongs to the technical field of characteristic evaluation of radar radiation source signals in electronic countermeasures, and in particular relates to a method and system for comprehensive evaluation of intrapulse characteristics of radar radiation source signals. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: the comprehensive evaluation of intrapulse characteristics of radar emitter signal (RES) is a new problem that needs to be solved urgently in modern radar countermeasures. In the modern radar countermeasure signal environment, the number of radiation sources is large, the distribution density is large, and the signals overlap seriously. It is difficult for the traditional signal identification method to adapt to the modern complex electromagnetic environment. The research on radar signal sorting and recognition is a very important and very difficult subject in the...
