Problems solved by technology

At present, the intelligence radar equipment currently in service at home and abroad usually does not have the ability to identify targets, and can only provide information on motion parameters such as the target's position, altitude, and speed.

Embodiment Construction

[0035] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0036] The present invention relates to the target RCS real-time evaluation method of radar application as follows:

[0037] a) After the radar echo signal is sampled by AD and processed by digital signal, for the target or clutter original traces that pass the detection threshold (constant false alarm detection detection, clutter map detection threshold), output the position and amplitude information of the original traces ;

[0038] b) When the original dots are condensed, the original dots are grouped in space according to the designed agglomeration gate, and a group of dots (at least two original dots) with very close spatial positions are used as an original dot group to carry out Agglomeration processing, each original dot trace group forms a cohesive dot trace after agglomeration processing, and transmits the position and amplitude information of the aggl...

Abstract

The present invention relates to a radar application-based target RCS real-time evaluation method. According to the method, firstly, echo signals are subjected to AD sampling and digital signal processing, and then original track points are outputted. Secondly, original track points are subjected to coagulation treatment and coagulated track points are subjected to flight track treatment. In thisway, track points are obtained. Thirdly, the amplitude of track points is subjected to distance and STC correction, and the amplitude value of an outputted flight track is subjected to real-time meanstatistics. According to the region of the statistical result of the amplitude mean of a target flight track, the RCS value of the target is estimated. The method can be applied to the RCS real-time evaluation of a to-be-tested target based on radar equipment and is applicable in engineering application conditions.

Description

technical field [0001] The invention belongs to the field of radar technology, specifically the field of target recognition technology, relates to a new method for real-time evaluation of the RCS of a measured target, can be applied to radar equipment for real-time evaluation of the RCS of a measured target, and has engineering application conditions. Background technique [0002] As the so-called know yourself and the enemy, you will never end up in a hundred battles. In modern warfare, radar equipment is the main means of battlefield situation awareness. The more information you can get about the enemy's incoming targets, the more important it is for your side to make targeted deployments in advance; therefore, modern warfare Higher and higher technical requirements are put forward for radar equipment, and radars are required to provide information such as the number, type (or even model) of incoming targets. [0003] The relatively extensive and mature technologies for so...
