AI Technical Summary

Technical Problem

Traditional single-station radars cannot meet the requirements of rapid detection and accurate identification of stealth targets, and the distributed multi-station radar anti-penetration range calculation model lacks a quantitative model and cannot effectively express its anti-penetration capability.

Method used

A multi-station radar joint anti-penetration range characterization model is constructed. By randomly generating a distributed multi-station radar layout and combining the multi-dimensional electromagnetic scattering characteristics of stealth targets, the echo power of the target at each grid and rotation angle is calculated, and the grid area with an angle detection ratio of 1 is defined as the anti-penetration range.

Benefits of technology

It achieves full coverage detection of stealth targets and provides a simple and efficient anti-penetration range characterization method, which can evaluate the combat capability of the radar system and adapt to different detection needs.

Abstract

The present invention relates to the field of deep space target tracking and control, and discloses a method for characterizing the anti-penetration range of a multi-station radar joint operation. The implementation process is as follows: first, the monitoring area is divided into grids, and the maximum echo power corresponding to each radar transceiver combination when the target is in a certain grid and at a certain rotation angle is calculated to determine whether the target can be detected. Then, the number of times the target can be detected at each rotation angle is counted, and the angle detection ratio is calculated. Then, all grids in the monitoring area are traversed, and the detection ratio of the target at each grid position is calculated in turn. Finally, the grid area with a detection ratio equal to 1 is counted as the anti-penetration range. The present invention provides an anti-penetration range in which the target can be detected at all angles and areas. At the same time, the detection ratio can be defined according to different actual detection requirements, thereby obtaining the corresponding anti-penetration range. At the same time, the method can also provide guidance for optimizing radar node layout. The application is relatively simple and flexible, and has important academic significance and engineering application value.
