| 摘 要： | 利用模糊函数模糊图,对脉冲调频波形的探测性能进行分析,就波形的调频步长、子脉冲宽度、调制频偏等参数对测距性、测速性以及抗干扰性能的影响进行了分析与探讨,特别就波形参数脉冲重复周期与子脉冲宽度之比H对模糊图的影响进行了详细地分析.在此基础上得出脉冲调频探测的距离、速度分辨力、测距精度、测速精度等表达式,结果可为波形设计提供依据.

| Abstract: | Analyzes the detective performance of pulse frequency modulation waveform. From an analysis of the effects of different waveform parameters such as frequency modulation step length, child pulse width and the modulation frequency deviation on range detection, velocity detection and anti jamming ability, especially through a detailed analysis on the effect upon the picture of ambiguity as a result of the ratio of pulse repetition period and child pulse width, expressions giving pulse frequency modulation detection range, velocity resolution range accuracy and velocity accuracy are derived, thus providing a foundation for waveform design. |

| Keywords: | pulse frequency modulation ambiguity function ambiguity of velocity detection ambiguity of range detection |
