An Active Sensor Management Method Based on Risk Theory

Abstract

The invention discloses an active sensor management method based on risk theory, comprising the following steps: firstly, establishing a target risk model by using the risk theory; then, a calculation method of sensor radiation risk and sensor tracking error is given to quantify potential losses; The objective function is established with the minimum weighted sum of the two risks as the optimization objective. In order to obtain better combat benefits and improve the efficiency of solving the objective function, the convex optimization toolkit is used to solve the objective function. The invention uses the risk theory to build a model, builds the objective function according to the sensor radiation risk and the sensor tracking error, and uses the convex optimization theory to optimize and solve the objective function to obtain the optimal solution of the objective function, thereby improving the solving efficiency of the objective function.

Description

technical field [0001] The invention relates to the technical field of sensor management, in particular to an active sensor management method based on risk theory. Background technique [0002] At present, modern warfare has transformed from a traditional battlefield to an information battlefield, and the battlefield situation plays a crucial role in national defense and security. The types of information obtained by different types of sensors are complex. How to quickly select a suitable sensor and accurately obtain target measurement information is very important for battlefield evaluation. Therefore, the sensor management method is born. Sensor management aims to reasonably allocate limited sensor resources to complete the task of detecting, tracking and identifying targets. [0003] At present, in order to reasonably realize sensor management, researchers have successively proposed a variety of effective methods and technologies. The sensor management method based on i...

The sensor management method based on information theory is widely used. In the article "Sensor Control Method Based on Information Entropy Measurement in Multi-Target Tracking", Chen Hui and others established the performance function of sensor management through information entropy, and constructed the performance function of sensor management by using the performance function. The basic framework, although this method has good technical indicators, but in order to consider the actual combat needs; Zhang Hongbin and others used fuzzy reasoning and neural network sensor management method The single platform has been extended to multiple platforms, and at the same time, the effective allocation between the sensor and the target has been realized. Although this method can achieve a good estimation of the target state, the efficiency of solving the target function is low, which is not conducive to the real-time information processing in the battlefield environment. In the article "Airborne Multi-Sensor Resource Allocation Model Based on Linear Programming", Gong Hua et al. used the sensor management method based on linear programming to establish a management model and optimize the objective function through the sensor performance function and matching function matrix. The solution problem of multi-sensor allocation, but this method does not consider the impact of various external environmental risks and sensor radiation on multi-sensor allocation
