Embodiment Construction

[0012] The multi-mode tracking is mainly completed by the radar task scheduling module. The task scheduling module receives the track information of the target in real time, the information of the interference source, receives the clutter map and the shutter threshold information, etc., and judges which type of target is to be tracked and irradiated according to the received information. Track the model. Build a library of tracking patterns. There are 6 tracking models stored in the model library. For each tracking beam dwell application, select the corresponding model from the model library. Calculate relevant parameters, distances, determine periods, etc.

[0013] The specific implementation steps of the present invention are as follows, see figure 1 .

[0014] ① The task scheduling module receives the tracking request of the target whose track has been established. After receiving the request, find the target's track from the target track library, extract the target's t...

Abstract

The invention relates to an object multi-mode tracking method based on a phased array system radar, wherein the method is mainly used for object tracking of a radar system. According to the method of the invention, a characteristic that a tracking task wave beam parameter of the phased array system radar can be compiled is utilized; a plurality of typical object tracking modes is arranged; and a matched mode is adaptively selected for tracking according to object tracking quality, object echo strength, object motility, clutter condition around the object and interference condition in the tracking process. The object multi-mode tracking method can improve object tracking stability and save radar resource. The object multi-mode tracking method has wide application prospect in a radar object tracking field.

Description

technical field [0001] The invention belongs to phased array radar target tracking technology, in particular to a target multi-mode tracking method based on phased array system radar. Background technique [0002] The traditional radar transmission waveform has nothing to do with the environment. During the transmission process, no received information is used to feed back to the transmitter. Each transmission repeats the same waveform, and the transmission waveform is not changed according to the acquired information to achieve the best environment. Optimal matching and other issues. Professor Simon Haykin proposed the concept of cognitive radar in 2006. [0003] Traditional radars usually use fixed transmitting signals, adaptively process the received echoes at the receiving end, and improve performance through the design of filtering algorithms. Since the tracking performance of the radar to the target depends to a large extent on the transmitted waveform, for the incre...
