Embodiment Construction
[0051] refer to figure 1 . The specific steps of the performance evaluation method for low probability of interception of stealth radar of the present invention are as follows:
[0052] 1. Establish a frame structure model for stealth radar LPI performance evaluation.
[0053] In the present invention, the frame structure model of stealth radar LPI performance evaluation includes L1-L4 four-level hierarchical structure, and the elements of each level play a dominant role on the subordinate elements of the next level, and at the same time, it is dominated by the elements of the previous level. The relationship of dominance from top to bottom forms a hierarchical hierarchy. The specific meaning is as follows:
[0054] ① Target layer (L1): performance verification of stealth radar LPI;
[0055] ② Sub-target layer (L2-1~L2-2): including two branches of "anti-reconnaissance ability L2-1" and "anti-sorting and identification ability L2-2";
[0056] ③ Criterion layer (L3-1~L3-8)...

The invention discloses a stealth radar low interception probability performance assessment method, which is used for solving the technology problem that the LPI performance assessment method of the prior art is poor in practicability. The stealth radar low interception probability performance assessment method comprises steps of dividing the factors (like the radar waveform design, power management and radar hardware design which includes the low side lobe antenna and a high processing gain receiver ) and the measurements that affect the radar LPI performance into a plurality of groups according to the different properties from the aspects of the time domain, the space domain, the frequency domain and the power domain, forming a target layer L1, a sub-target-layer L2-1-L2-2, a criterion layer L3-1-L3-8, a sub-criterion layer L4-1-L4-l7, performing every two comparison on factors through level analysis, determining the relative importance of various factors in the same layer, comprehensively determines the contribution weight of the various layers, the various factors and the various reference values relative to the LPI performance, and obtaining the quantitative assessment results of the LPI performance of various radars in order to evaluate the LPI performance of the various radars. As a result, the assessment result is more close to the practical condition, and the practicability is stronger.
Description
technical field [0001] The invention relates to the field of information technology, in particular to a low intercept probability performance evaluation method for stealth radar. Background technique [0002] Radar belongs to active detection. When the electromagnetic wave emitted by the radar is detected by the other party's detection equipment, it is called intercepted. Generally speaking, being intercepted is usually regarded as a necessary condition for being attacked, so the conventional radar low probability of intercept (hereinafter referred to as LPI) technology research usually takes reducing the electromagnetic power of radar as the main goal, and the interception factor α is used as the evaluation index. [0003] However, in modern electronic warfare, the interception of radar electromagnetic waves does not mean the effectiveness of the attack, but depends on the sufficiency of the intercepted information—full information or partial information. If the radar infor...
