Abstract:
The existing numerical relations of resolution and pulse trains of frequency modulated (PTFM) signal’s parameters are presented by narrowband ambiguity function in narrowband condition. In wideband condition, the resolution of PTFM should be analyzed by the wideband ambiguity function (WAF), but it is complicated to directly solve the resolution equation based on WAF. A numerical resolution analyzing method based on WAF is proposed. Resolution is expressed as the successive form of multiplication of each single parameter’s function, by combined applying of equation extracting and curve fitting methods, each single parameter’s function is educed, then the expression of resolution can be synthesized. Analyzing results show that the proposed methods can clearly uncover the numerical relations of resolution and signal’s parameters in wideband condition. These numerical relations have instructible meaning for PTFM’s parameters designing, the proposed numerical resolution analyzing method has a special reference value to other wideband signal forms.
