Embodiment Construction

[0016] The present invention proposes a phased array tracking resource adaptive scheduling method based on target classification. Based on specific speed and altitude thresholds, tracking targets are roughly divided into fixed-wing, fixed-wing / helicopter, civilian sea targets, and unidentified sea targets / These four types of helicopters. According to the motion characteristics of these four target types, a tracking mode library is established. The adaptive tracking of targets in the phased array system is mainly completed by the radar task scheduling module. The task scheduling module receives the target's track information, interference source information, clutter map and shutter limit information in real time, and calculates the target's speed and height information. According to the calculation results, it is judged that the tracking and irradiation of the target will be in the tracking mode library. Which tracking mode is used to determine the data rate, signal encoding f...

Abstract

The invention relates to a target classification based phased array tracking resource self-adaptive scheduling method. The method includes: receiving target track information and interference source information in real time; receiving a clutter map and fast threshold information and the like; performing target classification according to the received information; dividing targets into four targettypes on the basis of the speed and the altitude; establishing a tracking mode library for the motion characteristics of the four target types; selecting the corresponding tracking mode from the modelibrary for the tracking beam resident application of different targets; and determining tracking parameters such as the data rate, the pulse number, the pulse width, and the repetition period to achieve self-adaptive configuration of tracking resources.

Description

Technical field [0001] The invention belongs to the technical field of phased array radar target tracking. Background technique [0002] In view of the fact that the traditional radar transmission waveform has nothing to do with the environment, no received information is fed back to the transmitter during the transmission process. The same waveform is repeated for each transmission, and the transmission waveform is not changed according to the acquired information to achieve the best environment. Excellent matching and other issues. Professor Simon Haykin proposed the concept of cognitive radar in 2006. [0003] Traditional radar usually uses a fixed transmit signal, adaptively processes the received echo at the receiving end, and improves performance through the design of filtering algorithms. Since the radar’s tracking performance of the target depends to a large extent on the transmitted waveform, for the increasingly complex battlefield environment, dense clutter, multi-targ...
