Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] In conjunction with the accompanying drawings, the present invention provides a multimode radar signal sorting method based on data field hierarchical clustering, which mainly includes the following steps:

[0031] Step 1: Randomly extract multi-mode radar signals from the multi-mode radar signal sample set D to establish a data space Ω, and the multi-mode radar signal sample set is D consisting of radar signal arrival direction DOA, pulse width PW, and carrier frequency RF Composition of characteristic parameters, data space Ω contains the extracted data set D'={x 1 ,x 2 ,...,x i ,...,x n}, where the data point x i , i=1~n,

[0032] The formula for calculating the potential value of a data point x in the data space Ω is:

[0033]

[0034] Where ||x-x i || is the data point x to any point x in the data space i The Eu...

Abstract

The invention provides a multi-mode radar signal sorting method based on data field hierarchical clustering. The multi-mode radar signal sorting method includes steps: building a data field model according to intercepted radar sample signals; optimizing influence factors of a data field, dividing grids, and drawing equipotential lines; searching potential values of a data space by employing an elimination potential method; and performing hierarchical clustering of radar signal characteristic parameters regarding all the potential values of the data space as the clustering center, and accomplishing the sorting of the multi-mode radar signals. According to the method, based on the characteristic parameters of the multi-mode radar signals, the sorting of the multi-mode radar signals is accomplished according to the data space property formed by the multi-mode radar signal parameters, the problem that matching increase frequently occurs during the sorting of the multi-mode radar signals is well solved, and the sorting precision is high.

Description

technical field [0001] The invention relates to the field of radar countermeasure information processing, in particular to a multimode radar signal sorting method based on data field hierarchical clustering. Background technique [0002] "Multi-mode radar" refers to a new type of radar that integrates the functions of multiple system radars, has multiple working modes, and can complete multiple combat tasks at the same time. In order to improve work performance and meet anti-interference requirements, multi-mode radars often use complex Due to the changing waveform design, the frequency and time-domain parameters of radar emission pulses undergo complex changes, and the radar signal characteristic parameters are complex and changeable in space, without obvious correlation and regularity. , anti-tracking capability and comprehensive combat capability requirements increase, and the application of multi-mode radar is becoming more and more extensive. Due to the increasingly adv...
