Embodiment Construction

[0039] refer to figure 1 , the concrete steps of the present invention are as follows:

[0040] Step 1, obtain the radar measurement value.

[0041] The status information of the maneuvering target is detected by the radar, that is, the position information, and it is sampled N times with T as the sampling interval to obtain a measurement value sequence {z k}, k=1,2,3...N.

[0042]Step 2, establishing a mathematical model for maneuvering target tracking.

[0043] Based on the fact that the state change process of the maneuvering target is a stochastic process, the target tracking problem can be modeled as a discrete-time stochastic hybrid system. The state equation and measurement equation of the hybrid system are as follows:

[0044] x k = F k x k - 1 + G k ...

Abstract

The invention provides a maneuvering target tracking method based on variable structure multiple models. The maneuvering target tracking method mainly solves the problems that in the prior art, target tracking accuracy is low and target tracking is not in time. The method includes the implementation steps that firstly, a target motion state detected by radar is sampled, and then a radar measured value is acquired; secondly, a maneuvering target tracking mathematical model is established according to target motion characteristics; thirdly, a maneuvering target motion model is established according to the target tracking mathematical model and is initialized; fourthly, through a model set adaptive strategy, a target motion model set at each moment is acquired; fifthly, according to the radar measured value and the target motion model sets, a variable structure interactive multi-model algorithm is operated, state estimation of a maneuvering target is acquired, and primary tracking of the target is achieved; sixthly, the fourth step and the fifth step are repeatedly executed until tracking is finished. On the premise that high tracking accuracy is guaranteed, the calculation quantity is reduced, and timeliness of maneuvering target tracking is improved.

Description

technical field [0001] The invention belongs to the technical field of signal processing, in particular to a tracking method of a maneuvering target. The present invention can be used to improve the timeliness of tracking while ensuring the tracking accuracy. Background technique [0002] Maneuvering target tracking has always been a research hotspot in the field of tracking. According to the number of target motion models used, maneuvering target tracking methods can be divided into single-model tracking and multi-model tracking. The multi-model approach has mainly gone through three generations. [0003] The first generation of multi-model method is called autonomous multi-model AMM, which was first proposed by Magill and Lainiotis, and later widely used and promoted by Maybeck et al. The characteristic of this method is that the number of models is fixed, each basic filter operates independently and independently of other filters, and finally the output is fused. Sinc...
