AMBIGUITY FUNCTIONS OF ONE CERTAIN CHAOTIC RADAR WAVEFORMS
一种混沌雷达波形的模糊函数

This paper presents one certain chaotic radar waveforms based on one-dimensional chaotic sequences. This paper derives theoretically the formulae of the ambiguity functions of two cases, i.e., (1) continuous chaotic radar waveforms; (2) rectangular pulse radar waveforms modulated by cut-off chaotic sequences. Such theoretical analysis and numerical simulations denote that the ambiguity functions of the first case are shaped by ideal thumbtacks, and those of the second case are shaped by sharp knife edges. These results hint that such chaotic radar waveforms have good range and velocity resolutions.
