Problems solved by technology

[0003] The traditional target extraction method based on radar spectrum data is to directly perform constant false alarm rate processing, and then perform target extraction. It does not consider the influence of fixed strong clutter on the zero channel and the channels near the zero channel on low-speed targets, which reduces the zero channel. and the ability to extract low-speed targets on the nearby channel of the zero channel, which led to false extraction of low-speed targets

Abstract

The invention discloses a target extraction method based on ground monitoring radar spectrum data. The target extraction method comprises the following steps that spectrum data information processed by a radar front end is obtained; the spectrum data information is subjected to cancellation processing of spectrum data to obtain spectrum data information after cancellation processing; constant false alarm rate processing is carried out on the spectrum data information after cancellation processing to obtain spectrum data information of a target, and a two-dimensional image is constructed according to the spectrum data information of the target; target edge extraction is carried out on the two-dimensional image to extract spectrum data information belonging to the same target; and ground object target filtering is carried out on the spectrum data information belonging to the same target to obtain spectrum data information belonging to the same target after the ground object target filtering. The target extraction method reduces the influence of fixed strong clutter on low-speed targets, improves the detection probability of the low-speed targets, and provides a reliable basis for subsequent target cluster and track processing.

Description

technical field [0001] The invention relates to the technical field of real-time target extraction of spectrum data of a ground surveillance radar system, in particular to a target extraction method based on ground surveillance radar spectrum data. Background technique [0002] The target extraction method is to extract the information belonging to the same target contour and contour, and estimate the target parameters according to this information, so as to achieve the purpose of improving the accuracy of point track aggregation and improving the quality of track tracking. Therefore, choosing the optimal target extraction method is crucial to accurately estimating the target parameters. [0003] The traditional target extraction method based on radar spectrum data is to directly perform constant false alarm rate processing, and then perform target extraction. It does not consider the influence of fixed strong clutter on the zero channel and the channels near the zero channe...
