Description

technical field [0001] The invention belongs to the technical field of identification and evaluation of radiation source signals in electronic countermeasures, and in particular relates to a radiation source signal identification performance evaluation method, system, intelligent terminal and application. Background technique [0002] At present: In the field of electronic countermeasures, there is no complete theoretical system for evaluating the effectiveness of radiation source signal identification. The main reasons for this phenomenon can be attributed to three aspects: First, the classifiers used in radiation source signal identification methods are various and have different performances , it is impossible to give a single evaluation standard; the second is that the signal characteristic parameters identified by the radiation source signal identification method are different, so the ability to characterize the signal information is also different; the third is that the...

Problems solved by technology

[0005] (2) Correlation factors are not considered between evaluation indicators: the methods proposed in the existing literature assume that each indicator is independent of each other, but in actual application, most of the evaluation indicators are related

[0006] (3) Unable to achieve wartime assessment: Most of the existing assessment algorithms, although the assessment results are highly accurate and can be used for the construction and development of post-war electronic countermeasures forces, cannot achieve wartime assessment

For the evaluation of identification effectiveness based on actual combat simulation, although wartime evaluation can be realized, it is costly and the environmental simulation conditions are extremely harsh, so it is difficult to obtain evaluation results with strong versatility and high accuracy

[0007] The difficulty in solving the above problems and defects is: at present, in the field of identification and evaluation of radiation source signals in electronic countermeasures, there is no complete technical solution analysis index correlation relationship, and scholars have not considered the impact of this feature on evaluation in their research. , so the available reference materials are very limited

In addition, the evaluation methods used in the existing research results cannot perfectly avoid their own defects, and there is no practical coping strategy for special situations, which greatly reduces the universality of the algorithm

In addition, the evaluation algorithms proposed in the existing research results are all designed for the post-war period and cannot meet the requirements of real-time evaluation on the actual battlefield.
