Abstract:

Considering that the traditional emitter threat assessment methods are difficult to reflect the degree of target threaten intuitively and the deficiency of real-time and complexity, on the basis of the radar chart method (RCM), an algorithm of combined emitter threat assessment based on improved combination weighting (ICW)-RCM is proposed. Coarse sorting is integrated with fine sorting in combined emitter threat assessment. Firstly, sequence the emitter threat level roughly according to the radar operation mode, and reduce task priority of the low-threat emitter. Then, on the basis of ICW-RCM, sequence the emitters with the same radar operation mode. Finally, obtain the results of emitter threat assessment which combines coarse sorting and fine sorting. Simulation analyses show the correctness and effectiveness of this algorithm. Comparing with classical methods of emitter threat assessment based on CW-RCM, the proposed algorithm is visual in image and can work quickly with lower complexity.
