Abstract

In order to further improve the ability of detecting and evaluating the detection performance and interference effect of the integrated signal, a quantitative analysis method (K-means quantization) for pulse compression is proposed. The method is based on the amplitude analysis of the pulse compression results. By using the improved K-means clustering method, the recognition degree of the selected target points is obtained by induction and analysis. The simulation results show that the analysis of the detection performance or interference performance of the integrated signal is consistent with the traditional analysis conclusion by using K-means quantization method. It has better measurability, objectivity and independence, which can be used for automatic evaluation of the system..

In order to synthesize the advantages of these methods, to improve the detection performance of the integrated signal and the ability to evaluate and analyze the interference effect, and to achieve the purpose of the performance of the automatic discriminant system, a method of quantitative analysis of the results of pulse compression
According to formula (5), it is obviously that if the recognition degree used for signal ability analysis, the higher the P value, the better the signal pulse compression results; If used for the assessment of interference effects, the lower the P value, the better the jamming effect

INTRODUCTION

In the detection performance analysis of integrated signal, the quantitative parameters such as radar detection are commonly used as evaluation indexes. In order to synthesize the advantages of these methods, to improve the detection performance of the integrated signal and the ability to evaluate and analyze the interference effect, and to achieve the purpose of the performance of the automatic discriminant system, a method of quantitative analysis of the results of pulse compression It is obviously that the result of pulse compression has higher amplitude in target corresponding position, while the amplitude of other locations is much lower than the target location This characteristic is used to measure the detection ability of signals. According to formula (5), it is obviously that if the recognition degree used for signal ability analysis, the higher the P value, the better the signal pulse compression results; If used for the assessment of interference effects, the lower the P value, the better the jamming effect. The algorithm process uses a flow chart as follows: Start
