  • 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 casess,i.e.,(1) continuous chaotic radar waveforms;(2)rectangular pulsse raaar 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 iedal 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.
