摘要 OFDM(正交频分复用)雷达是近年来兴起的一种新体制雷达。由于其具有大时宽带宽积、良好的抗干扰性能、较高的频谱利用率和易于数字化处理等诸多优点近年来备受关注。OFDM雷达信号属于大时宽带宽积信号,在运用窄带模糊函数分析时具有一定的局限性,首先给出了OFDM雷达信号的回波模型,在此基础上推导出信号的宽带模糊函数表达式,分析了OFDM雷达的时频分辨性能。分析表明,OFDM信号具有近似图钉型的模糊函数,该结果可用于OFDM雷达系统的设计分析。 OFDM(orthogonal frequency division multiplexing) radar is a new radar system and is concerned by researchers since it has many strongpoints,such as large time-bandwidth product,good anti-jamming capability,high spectrum efficiency,simple digital processing and so on.OFDM radar signal is large time-bandwidth product signal,the use of narrowband ambiguity function has some limitations.This paper gives the OFDM radar echo signal model and the wideband ambiguity function expression,analyses the resolution performance of the OFDM time-frequency.The analysis shows that this signal has similar thumbtack ambiguity function.The result can be used in the design of OFDM radar system.
