specific Embodiment approach 1

[0019] Specific implementation mode 1. Combination figure 1 Describe this specific implementation mode. On the basis of the traditional radar signal sorting algorithm and the analysis of the current electromagnetic environment, the present invention recognizes the problem of fast optimal boundary division of multi-system radar signals with overlapping parameters in the current complex and high-density environment. It has become a difficult problem restricting the development of signal sorting field. The hard classification and sorting method of the traditional sorting algorithm cannot effectively deal with it, ignores the intermediary of overlapping samples, and cannot objectively reflect the real world.

[0020] In view of the above problems, the present invention proposes a new radar signal sorting method based on cloud model joint geometric coverage. The present invention firstly introduces the concept of geometric coverage into radar signal sorting, describes the distribu...

Abstract

The method discloses a method for sorting signals of a radar radiation source by using coverage in a complex dense environment and relates to a radar radiation source signal sorting method by using coverage, aiming at solving the problem of poor sorting ability of the prior art in the complex dense environment as well as in a serious overlapping condition of characteristic parameters. The method comprises the following steps of: choosing the characteristic parameters of a radar signal capable of being standardized as input characteristic vectors, initializing a radar signal sample parameter space; carrying out supervisory learning on the radar signal with parameter prior information in the radar signal sample parameter space by using a coverage algorithm; separating the radar signals of different kinds by using different fields by using the coverage algorithm; expressing the membership degree of the characteristic parameters of each radar signal to be sorted and identified in relative with each field by using a cloud model, and obtaining the membership value of the membership degree of the radar signal to be sorted and identified in relative with each field; and sorting the signal to be detected by using decision rules. The method for sorting signals of the radar radiation source by using coverage in the complex dense environment is suitable for sorting radar radiation source signals.

Description

technical field [0001] The invention relates to a radar radiation source signal coverage sorting method. Background technique [0002] With the rapid development of electronic technology, more and more missile-guided weapons are widely used in modern warfare, resulting in complex and dense radar radiation source signals in the electronic reconnaissance environment. A large number of multi-functional and multi-purpose modern new system radars have appeared, so that a radar may have multiple working states, and the parameters of the radar emitter signal present complex changes. Modern system radar has the characteristics of random changes in various parameters, and may have the random agility and jitter capabilities of carrier frequency (RF), pulse width (PW), azimuth angle (DOA), pulse repetition period (PRI) and other parameters at the same time, resulting in There is serious overlap in the radar signal parameter space expressed by conventional signal sorting parameters. D...
