Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] The general performance simulation method of air surveillance radar, in a nutshell, the steps are as follows:

[0025] 1) Input the air situation signal to be detected by the simulated radar;

[0026] 2) Send the above-mentioned air condition signal into more than one simulation channel, one of which is the target processing simulation channel; the computer processes each simulation channel in parallel, and each simulation channel outputs the corresponding original video signal and detection video signal;

[0027] 3) The original video signals of each simulation channel are data aligned and superimposed to form original video information, the detection video signals of each simulation channel are data aligned and superimposed to form detection video information, and dot trace aggregation is performed to form dot trace output.

[0028] Such as figure ...

Abstract

The invention relates to a general performance simulation method and a framework of an air surveillance radar. General real-time simulation of detection performance of the air surveillance radar is achieved due to the utilization of a structure of a plurality of serial simulation module channels and parallel computation processing calculation channels. Processing modules related to the radar are serially connected through the serial simulation module channels according to treating processes of radar real installation signals to form into a simulation process of processing of at least a radar signal. Parallel simulation calculations of treating processes of a target signal, an interference signal and a clutter signal are respectively performed through a parallel calculation processing structure based on the serial simulation module channels and then various signals are performed composition and point trace cohesion to form and output a radar simulation result. The serial simulation module channels are reconfigurable; module composed structures and parameters can be changed; and an existing module or a new construct module can be utilized to achieve general performance simulation of the air surveillance radar.

Description

technical field [0001] The invention relates to a method for simulating general performance of an air surveillance radar. Background technique [0002] In the field of radar research and application, computer modeling and simulation has become one of the important supporting technologies in the process of equipment demonstration, design, development, experiment, evaluation, training and use. It is not restricted by many conditions such as climate and airspace, and it saves money and is risk-free. Computer simulation has become a vital part of the radar field. [0003] At present, most general-purpose radar simulators at home and abroad are designed based on dedicated programmable radar hardware, which can realize radar simulation at the hardware signal level. The simulation performance parameters are variable, but the hardware structure is not changeable, which limits its flexibility and costs. high. As for the dynamic real-time general radar simulation technology based o...
