Abstract

The invention discloses a distributed moving platform area coverage rate calculation method based on a thermodynamic diagram, and the method comprises the following steps: S1, carrying out the grid division of a detection area, calculating the detection probability of each grid according to a predetermined air route of a moving platform where a radar is located and a radar equation, and accumulating the detection probabilities to obtain an area search coverage rate; s2, setting a route of a to-be-observed target, calculating the detection probability of the target at the moving moment according to the relative position of the to-be-observed target and the patrol radar and a radar equation, and accumulating the detection probability of the whole route to obtain area tracking coverage rate calculation; and S3, area detection and tracking performance evaluation: according to the above steps, evaluating whether the air route of the platform where the radar is located meets the detection and tracking requirements, if not, re-optimizing the air route, and if so, completing the evaluation. According to the method, the detection thermodynamic diagram is established through a particle sampling method, the detection times and data rate distribution of the focus region are directly analyzed, and the efficiency and the accuracy are improved.
