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] The present invention will now be further described in conjunction with the embodiments and drawings:

[0036] The real-time evaluation method of target RCS related to radar application of the present invention is:

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

[0038] b) In the process of condensing the original traces, the original traces are spatially grouped according to the designed condensing gate, and a group of traces (at least two original traces) in close spatial position are regarded as a group of original traces. Condensation processing, after agglomeration processing, each group of original points and traces form a condensed trace, and the position and amplitude information of the condensed trac...

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, and relates to a new method for real-time evaluation of the RCS of the measured target. It can be applied to radar equipment for real-time evaluation of the RCS of the measured target and has engineering application conditions. Background technique [0002] As the so-called knowing oneself and the enemy, a hundred battles are not dead. In modern warfare, radar equipment is the main means of situational awareness on the battlefield. The more information that can be obtained from the enemy's incoming target, the more important it is for the party to make targeted deployment in advance; therefore, modern warfare Higher and higher technical requirements are put forward for radar equipment, requiring the radar to provide information such as the number, type (or even model) of incoming targets. [0003] The more extensive and mature technologies to solve...
