Problems solved by technology

[0003] In terms of the visualization form of the radar detection range, the traditional method of visualizing the radar range with two-dimensional graphics and icons has been difficult to meet the current demand for realistic, vivid and intuitive situation display
At present, in terms of three-dimensional visualization of radar detection range, Yang Chao, Chen Peng, Wu Lingda and others (National University of Defense Technology) proposed to model radar electromagnetic waves by using parabolic equation and APM propagation model, considering various factors such as atmosphere and terrain However, the method of calculating radar electromagnetic wave attenuation using an advanced propagation model involves many factors and a huge amount of calculation, so it is not easy to implement in practice.
Qiu Hang, Chen Leiting and others (University of Electronic Science and Technology of China) studied the three-dimensional visualization of the radar range under the influence of terrain based on the radar equation, and made three-dimensional corrections to the boundary points of the radar model, but the three-dimensional visualization of the radar detection range under the electronic interference The effect is not realistic
Research on 3D visualization of radar detection range under active interference is mainly theoretical analysis, and the existing 3D visualization effects are not vivid and realistic, and cannot be well visualized for radar detection range under active interference

Abstract

The invention relates to a three-dimensional visualization method for the detection range under active jamming based on a radar equation. According to the invention, a calculation method for the radardetection range under active suppression jamming is deduced based on a radar detection range theory of the radar equation, various real parameters of radar are set, the parameter setting of a singleor multiple jammers is supported, the calculation is completed, and three-dimensional visualization of the radar detection range is achieved. Compared with the prior art, the three-dimensional visualization method for the radar detection range under active jamming is more realistic, visual and efficient.
