Problems solved by technology

The existing radar emitter signal feature analysis methods and radar emitter type identification methods are almost all aimed at fixed-value signal features, and cannot perform intuitive and detailed description and analysis specifically for the type identification capabilities of interval-type signal features
With the advancement of science and technology, the interval-type radar emitter data resources will continue to increase. If the interval-type radar emitter information cannot be fully and effectively utilized, a large amount of radar emitter information resources will be wasted.

Embodiment 1

[0065] Embodiment 1: This embodiment is an example of constructing a distribution histogram of interval-type signal features. Assuming that 17 samples of a type of radar radiation source are detected, the carrier frequency signal of each sample is an interval signal feature, and its value is shown in Table 1, and the unit is MHz. Construct a signal feature distribution histogram for the carrier frequency signal, assuming that the number of histogram intervals is 5, that is, NumBlk=5, the steps are as follows.

Embodiment 2

[0077] Embodiment 2: as image 3 and Figure 4 As shown, this embodiment is an example of calculating the coincidence degree of intervals of type histograms. Assume that after steps 1-6, three types of radar radiation sources (c 1 、c 2 and c 3 ) histogram interval distribution probability on two interval signal features (carrier frequency and repetition frequency), as shown in Table 3. Among them, the number of histogram intervals of the two interval-type signal features is 12, that is, NumBlk=12. According to steps 7-11, the optimal features for identifying each radar radiation source type are judged from the two interval-type signal features.

Abstract

The invention discloses a method for analyzing the identification capability of interval radar radiation source signal feature types. For the interval-type signal characteristics of different types of radar radiation sources, the histogram is used to describe the distribution range and probability, and on this basis, the distribution differences of the interval-type signal characteristics of different types of radar radiation sources are compared, and then the identification of each interval-type signal feature type is analyzed. The ability to identify, compare its strength, and output the optimal interval signal characteristics of each type of radar radiation source. The present invention has the advantages of: (1) it proposes a method for using histograms to describe the signal characteristics of interval-type radar emitters, which breaks through the limitation that the traditional intuitive graph only describes a single fixed data value; (2) based on the histogram description, it can be further analyzed and identify the optimal interval type features of each radar radiation source type; (3) The calculation cost is low, and the method engineering is realized.

Description

technical field [0001] The invention relates to the field of data analysis and processing of multi-type radar radiation sources, in particular to a method for analyzing signal characteristics of interval type radar radiation sources for type identification. Background technique [0002] As we all know, there are more and more signal features of today's radar radiation sources. In addition to the classic pulse descriptor features, more and more intra-pulse features appear. In addition, the types of signal features are becoming more and more complex. Most of the traditional signal feature types are continuous and discrete (see: "Statistics", Jia Junping, Tsinghua University Press, Applied Statistics Series Textbook, 2006.). Nowadays, interval-type signal features have also become an important type of radar emitter data. This is because, as the complexity of radar emitters increases, the types and forms of signal signatures become increasingly diverse. In addition, due to th...
