Method for rectifying errors of heterogeneous multi-sensor system

The invention discloses a method for rectifying errors of a heterogeneous multi-sensor system, belonging to the field of radar data processing. At present, few researches are about the heterogeneous sensor network error rectification technology; and in the methods, the typical method is to expand a systematical error into a target state equation as a component, namely realizing estimation of the systematical error by adopting a joint estimation method, thus when the method is used for specific solution, a state equation of a target needs to be established accurately (in actual engineering application, the real state of the target is often unknown), otherwise, mismatching of the state equation can directly influence the accuracy of estimation. To effectively solve the problem of real-time error rectification of the heterogeneous sensor network in the actual engineering application, a method for rectifying errors of a heterogeneous multi-sensor system based on a passive location principle is designed. Simulation verification proves that the error rectifying method is suitable for situation of networking by radar, ESM, infrared and other passive sensors, and has popularization and application values.
