AI Technical Summary

Problems solved by technology

In addition, the research on mobile sensor networks has not considered the limited characteristics of the sensor. When the sensor is under limited conditions, the sensor often has multiple working modes. In order to obtain the overall optimal Tracking performance, the coupling of sensor selection and tracking process and the coupling of sensor mode selection and tracking process must be realized at the same time

Abstract

The invention relates to a state limited movement multi-sensor placing and multi-target tracking method. The invention provides a selective placing algorithm of a state limited movement sensor based on linear programming against the state limited movement multi-sensor placing problem in multi-target tracking. The method uses a convex optimization process to select a best sensor and its input modal observation target with minimized sensor total power consumption as a criterion, and an approximate best sensor and a corresponding input modal are simultaneously selected through the algorithm, so the coupling of mobile multi-sensor selection and a tracking process and the coupling of the sensor modal and the tracing process are solved.

Description

technical field [0001] The invention belongs to the field of multi-sensor multi-target tracking, in particular to a state-limited mobile multi-sensor configuration and multi-target tracking method. Background technique [0002] In practical applications, the movement of sensors is often limited by the geographical environment. For example, the movement of ground mobile platforms is limited by roads, the movement of offshore mobile platforms is limited by sea lanes, and the movement of air mobile platforms is limited by air lanes. . When using these restricted mobile platforms to track targets, the restricted mobile characteristics of the platforms must be considered at the same time. This is the realistic basis of the present invention's research. In addition, the research on mobile sensor networks has not considered the limited characteristics of the sensor. When the sensor is under limited conditions, the sensor often has multiple working modes. In order to obtain the ov...
