Problems solved by technology

[0006] To sum up, the current variable data rate target tracking is mostly for a single target, and there are few multi-target variable data rate tracking algorithms, and the common disadvantage is that there is a contradiction between the complexity of the algorithm in actual use, the amount of calculation and the accuracy of target tracking

Embodiment Construction

[0077] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0078] At present, evolutionary algorithms are more effective in solving discontinuous, non-differentiable, noisy and multimodal problems. Among the evolutionary algorithms, the differential evolution algorithm has been widely concerned and used because of its simple principle, easy engineering implementation, less control parameters, high optimization efficiency, and good robustness. Based on this, the present invention proposes a multi-object variable data rate tracking device and method based on differential evolution. The invention can overcome the defects of the existing multi-target varia...

Abstract

The invention discloses a multiple-target variable data rate tracking device based on differential evolution and a method thereof. The method comprises the following steps of based on an unsensitive filtering method, determining a target tracking data time interval upper limit; according to the target tracking data time interval upper limit, setting a target tracking time interval set; initializing a population, and setting a cross probability factor and an iteration algebra, wherein the population is set according to a current target tracking number and the target tracking time interval set; according to a mask operation method, carrying out mutation operation on each individual in the population so as to acquire a variation individual; carrying out crossover operation on the individual and the variation individual so as to generate a progeny crossover individual; using a one-to-one greedy sieve to compare a child individual to a corresponding father individual and storing a better one to a next generation, wherein the child individual is the progeny crossover individual and the father individual is the individual corresponding to the progeny crossover individual; and repeating the step4 to step6 till that the iteration algebra is equal to a target iteration algebra.

Description

technical field [0001] The invention relates to a tracking device and a tracking method thereof in the field of radar technology, in particular to a differential evolution-based multi-target variable data rate tracking device and a tracking method thereof. Background technique [0002] Phased array radar is an advanced target detection and positioning equipment that replaces mechanical scanning with electronic scanning. Due to the use of computer control, it has the characteristics of flexible multi-beam pointing and dwell time, controllable spatial power allocation and time resource allocation, etc. . These characteristics determine that the phased array radar can quickly provide three-coordinate measurement data of large airspace and multiple batches of targets, and also has high measurement accuracy and resolution. Phased array radar has strong anti-interference ability and multi-task requirements. Among other indicators of phased array radar, it is difficult to summariz...
