Several variants of the mathematical model of target tracking in driver assistance radar system are considered in article, conclusions about the effect of radar sensor carrier maneuvering on the operation of the tracking algorithm are made. Structurally the article consists of an introduction, two parts and a conclusion. The introduction shows the timeliness of the topic and the goal of research.
The first part is devoted to the description of mathematical models of target tracking depending on the chosen coordinate system. The relations between kinematic parameters in the problem of target tracking are considered. They need to be taken into account when developing a target tracking algorithm for a radar sensor. Virtues and shortcomings of pointed methods are shown, application areas and restrictions of each method are also indicated.
In the second part, the effect of radar sensor carrier maneuvering on the accuracy of target tracking by the car locator is considered on the example of model situations. The results of simulation of tracking errors for several variants of the mathematical model of tracking targets in different maneuvering conditions are presented. Conclusions about the dependence of the error value on the model are made.
In conclusion, it is concluded that it is possible to improve the accuracy of the tracking algorithm in the moving coordinate system, due to the inclusion of the radar sensor for self-angular velocity measurement in the radar equipment.
