Abstract

The invention discloses a dynamic planning pre-detection tracking method for a heterogeneous clutter background, belongs to the technical field of radar target detection, and in particular relates to the technical field of faint target radar detection under the heterogeneous clutter background. According to the dynamic planning pre-detection tracking method for the heterogeneous clutter background, the position of sudden change of clutter power is judged first after receiving the radar data, clutters of different powers are respectively normalized, then the optimal target track is selected, and thus the clutters can be effectively inhibited in the absence of the information of the position of sudden change of the clutters and the prior power information of the clutters in two sides of the position of sudden change, the target track can be quickly detected, and the false alarm and neglected detection can be reduced.

Description

technical field

[0001] The invention belongs to the technical field of radar target detection, in particular to the technical field of radar detection of weak targets under the background of non-uniform clutter. Background technique

[0002] The dynamic programming tracking before detection algorithm is an effective weak target tracking method. It does not perform threshold detection in a single frame, and directly uses multi-frame joint processing of radar echo data, and searches all possible tracks through the accumulation of value functions, thereby estimating The true state of the target. It is easy to implement and can handle weak maneuvering targets, and has been widely used in radar tracking, computer vision and other fields.

[0003] The dynamic programming detection-before-tracking algorithm assumes that the background clutter is uniformly distributed, however, in actual radar scenarios, if the dominant interference comes from clutter instead of thermal noise or ma...
