【摘要】：照射源性能分析是外輻射源雷達(dá)領(lǐng)域的一個(gè)重要問題,針對(duì)一種非正交多載波調(diào)制信號(hào)即FBMC信號(hào),分析其用于多基地雷達(dá)照射源時(shí)的性能.推導(dǎo)了基于FBMC信號(hào)的空間非相干多基地平均模糊函數(shù)閉式表達(dá)式,在此基礎(chǔ)上以模糊函數(shù)-3,dB的投影面積為指標(biāo),分析了4種不同的雷達(dá)布站情況下多基地雷達(dá)系統(tǒng)的距離分辨性能.仿真結(jié)果表明,增加雷達(dá)發(fā)射站和接收站的數(shù)量均可以提高系統(tǒng)的距離分辨能力,而且在發(fā)射站和接收站數(shù)量一定的條件下,改變發(fā)射站部署會(huì)給距離分辨性能帶來(lái)明顯的改變..
[Abstract]:The performance analysis of irradiation source is an important problem in the field of external radiator radar. Aiming at a kind of non-orthogonal multi-carrier modulation signal, FBMC signal, the performance of radiation source used in multistatic radar is analyzed. The closed expression of spatial incoherent multistatic average fuzzy function based on FBMC signal is derived. on this basis, the range resolution performance of multistatic radar system under four different radar stations is analyzed by taking the projection area of fuzzy function-3 and dB as the index. The simulation results show that increasing the number of radar transmitting stations and receiving stations can improve the range resolution ability of the system, and under the condition of a certain number of transmitting stations and receiving stations, changing the deployment of transmitting stations will obviously change the range resolution performance.
