Description

Technical Field

[0001] The present invention relates to the technical field of electronic countermeasure and radar reconnaissance, and in particular to a radar radiation source information batching method and system for intelligence analysis. Background Art

[0002] Radar emitter batching is an important part of emitter identification processing in intelligence analysis. It can effectively eliminate false and repeated radar signals. In the process of radar intelligence analysis, if thousands or even tens of thousands of radar emitter information data are directly analyzed, many identical or similar information may be obtained, which is time-consuming to analyze and the intelligence analysis efficiency is low. If effective data batching can be performed, only hundreds or even dozens of useful emitter information data will be left, and several or even one desired information will be obtained, thereby improving the efficiency of radar intelligence analysis.

[0003] In the process of radar source batching, the identification information and style information are fully utilized to merge many sorting results into several effective radiation sources, so as to conduct rapid intelligence analysis and provide a basis for the next step of command decision-making. If there are phenomena of added batches, missed batches, and wrong batches in the batched data, some wrong radar recognition results will be given. Taking measures against these wrong radar recognition results will waste computing resources, reduce the recognition efficiency of the radar, and affect the real-time performance of radar recognition. Summary of the invention

[0007] Step 2, parse out the first radiation source information data and save it;

[0008] Step 3, parse out the second radiation source information data, and compare it with the saved data according to the batch number and radar model of the radiation source information. If the batch number and radar model are the same as those of the existing data, proceed to step 4; otherwise, proceed to step 5;

[0009] Step 4: Use any of the following methods to merge:

[0011] The second type is merging processing based on the interception time: for the radiation source in the non-disappearing state, the starting interception time of the radiation source information is compared with the final interception time of the saved radiation source information. If the difference is less than the time discrimination threshold, the batch operation is performed; otherwise, it goes to step 5;

[0046] u= a1*uRF + a2*uPRI

[0047] Where a1 and a2 are weight coefficients of the carrier frequency parameter and repetition frequency parameter, respectively, and a1+a2=1.

If the batch number and radar model are the same as those of the existing data, it enters the merging processing module; otherwise, it enters the circulation module;

[0056] The merge processing module uses any of the following methods to perform merge processing:

[0058] The second type is merging processing based on the interception time: for the radiation source in the non-disappearing state, the starting interception time of the radiation source information is compared with the final interception time of the saved radiation source information. If the difference is less than the time discrimination threshold, the batch operation is performed; otherwise, it goes to step 5;

[0059] The loop module saves the second radiation source information data and returns to the second analysis module to perform the batching process of the next radiation source information data; the batching operation of the radiation source information data is continued until the batching operation of all radiation source information data is completed.
