Embodiment Construction

[0060] like figure 1 As shown, this embodiment includes the following steps:

[0061] Step 0: Collect the evaluation index data in the radar countermeasure effectiveness evaluation test.

[0062] Step 1, the single-value data is converted into an interval value:

[0063] In this embodiment, the radar countermeasure effectiveness evaluation is taken as an example, and the single value data collected by the radar is shown in Table 1. Use "*" to indicate missing data, among which: c1~c6 indicate the evaluation index parameters collected in the test, and the effectiveness level refers to the combat effectiveness level of the evaluated object (radar countermeasure system) under certain circumstances.

[0064] In the filling process below, take filling the data of c4 in the first group as an example.

[0065]

[0066] Table 1. Radar countermeasure effectiveness evaluation single value data

[0067] The converted interval values ​​are shown in Table 2, where the data in each c...

Abstract

The invention relates to a radar countermeasure effectiveness optimized detection method. The method includes the steps that a subset comprising missing data indexes is determined, the weight coefficient of weighing generalized information entropy is calculated, and then the weighing generalized information entropy (namely original information entropy) of an initial subsystem is calculated; the searching starting point is determined, the step size in searching is set to add miniature section data so as to replace missing data, and the section lower limit of the missing data is determined and calculated; the section length is increased according to the step size, the weighing generalized information entropy at the global minimum position, the position where new information entropy is equal to original information entropy and the weighing generalized information entropy corresponding to the position are obtained, and the missing data is obtained through section judgment. The method of filling the missing data in a radar countermeasure effectiveness evaluating system is capable of improving the filling accuracy, well adaptive to a small sample data set and high in feasibility.

Description

technical field [0001] The invention relates to a technology in the field of wireless communication, in particular to a radar countermeasure effectiveness optimization detection method. Background technique [0002] Efficiency evaluation is a measurement of the degree to which a system can complete a certain task under specific conditions. The process of system efficiency evaluation is actually a decision-making process. In this process, the input data is the performance of each system index collected in the test. parameters, the output is the result of comprehensive performance. In the evaluation process, the evaluation index system should be established first, and then the index parameters can be obtained through different test conditions. However, some index parameters are often missing during the test. For example, unexpected events such as sensor failure, over-range measurement, privacy protection, and file loss may lead to an incomplete original database, which we ca...
