| Abstract: | The ambiguity function of intra-pulse chirp and inter-pulse stepped frequency signal is analyzed and obtained according to new type radar.Firstly,the expression of the signal is given.Then the concrete expression of ambiguity function of the signal is derived in accordance with the negative-type definition of ambiguity function.Last the brief analyzing of the ambiguity function is completed and the conclusion that the signal can achieve the high resolutions of range and speed is proved.Making use of the signal,a test system is developed and the ability of high range resolution is verified. |
