Problems solved by technology

[0002]Currently, in the process of radar interception, the radar system usually takes the sidelobe as the target for interception and tracking processing, which affects the working efficiency of the radar
The traditional method is to adjust the antenna to achieve low sidelobes, but doing so will affect the gain of the antenna, thereby affecting the detection performance of the radar

Embodiment Construction

[0021] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0022] Such as figure 1 As shown, it is a schematic flow chart provided by an embodiment of a sidelobe suppression method of the present invention. The sidelobe suppression method includes:

[0023] S1, intercepting the target detected by the radar for the first time, and obtaining the first intercepted echo.

[0024] It should be understood that the first interception of the target detected by the radar refers to the interception of the track of the target detected by the radar, and the input parameters may include the position information of the track, the distance R of the track d , dot trace direction A d , dot pitch E d , control attenuation MGC d , the size of the emission front TRSend d and the recei...

Abstract

The invention discloses a sidelobe suppression method and system, and relates to the field of radar. The sidelobe suppression method comprises the steps of performing first interception on a target detected by the radar; calculating parameters of a first interception echo; judging whether the target is a sidelobe or not according to the parameters, if so, terminating the interception, otherwise, performing second interception on the target; calculating parameters of a second interception echo; and judging whether the target is a sidelobe or not according to the parameters, if so, terminating the interception, otherwise, tracking the target. According to the sidelobe suppression method provided by the invention, interception is performed on the echo twice, whether the target is a sidelobe or not is judged according to the parameter of the echo, and if so, the tracking is not performed. The echo is judged according to the above method, so that the sidelobe can be effectively suppressed,and the gain of an antenna and the detection performance of the radar are not affected.

Description

technical field [0001] The invention relates to the field of radar, in particular to a side lobe suppression method and system. Background technique [0002] At present, in the process of radar interception, the radar system usually regards the sidelobe as the target for interception and tracking processing, which affects the working efficiency of the radar. The traditional method is to adjust the antenna to achieve low sidelobes, but doing so will affect the gain of the antenna, thereby affecting the detection performance of the radar. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sidelobe suppression method and a sidelobe suppression system aiming at the deficiencies of the prior art. [0004] The technical scheme that the present invention solves the problems of the technologies described above is as follows: [0005] A sidelobe suppression method, comprising: [0006] Carry out the first interception o...
