Abstract

The invention provides a multi-sensor multi-target joint detection, tracking and classification method, which is characterized in that it includes the following steps: S1: given the initial value of the multi-target state, defining a new Bayesian risk; S2: in the Under the conditions of the category assumptions in the above category hypothesis set, predict the multi-target state to obtain the prior state distribution of multiple targets; S3: under the condition of the category decision set, calculate the multi-target posterior density at time k, and obtain the posterior Check the state distribution of multiple targets; S4: Calculate the multi-target detection loss, state estimation loss and classification loss under different decision-making conditions; S5: According to the detection loss, state estimation loss and classification loss, the multi-target Estimation and Classification Optimal Solutions of Objectives. The method is easy to implement and provides important technical support for multi-sensor network environment perception system.

Description

Technical field [0001] The present invention relates to object detection sensor technology, particularly to a multi-sensor multi-target joint detection, tracking and classification. Background technique [0002] Joint multi-sensor multi-target detection, tracking and classification is an important and complex issue battlefield environmental monitoring need to be addressed. To solve this problem is to monitor the area of ​​military targets (ships, aircraft, missiles) detection, tracking and identification. In practical applications, poly (heterogeneous) network is a common sensor means. The system generally includes a plurality of types of sensors, such as radar (the Radar), infrared (IR), Electronic Support (the ESM), Identification Friend or Foe (IFF) and the like, using the measuring and the complementary information between the sensor fusion, the target can be improved the probability of finding a comprehensive tracking accuracy, and recognition accuracy. [0003] To solve thi...
