Abstract

The invention belongs to the field of radar signal processing, and relates to a method for forming a two-dimensional profile clutter map of a fixed platform radar for earth observation. The steps of forming a two-dimensional contour clutter map are as follows: range-wise pulse compression processing; double-pole filtering; performing range-dimensional clutter detection to form a range-azimuth two-dimensional matrix; forming a range-azimuth two-dimensional matrix for multiple scan cycles; Range-azimuth two-dimensional mean matrix; forms two-dimensional contour clutter map. The present invention proposes a method for forming a two-dimensional contour clutter map of a fixed platform radar for earth observation, using the formed two-dimensional contour clutter map to suppress the clutter of fixed buildings and other fixed reflectors on the ground, reducing the Target false alarm probability.

Description

A Method for Forming Two-Dimensional Contour Clutter Map of Ground Radar technical field The invention belongs to the field of radar signal processing, and relates to a method for forming a two-dimensional profile clutter map of a fixed platform radar for earth observation. Background technique For the fixed platform earth observation two-coordinate radar, except for the specific target to be observed, the fixed buildings and other fixed reflectors on the ground are all clutter. In order to reduce or even eliminate the influence of this kind of special clutter on the normal detection of targets, clutter suppression processing is required, and clutter suppression needs to obtain the two-dimensional contour clutter map of the surrounding ground object environment of the radar position first. At present, there is no public literature about obtaining the two-dimensional contour clutter map of the ground object environment around the radar position. Contents of the invention ...
