Paper Abstract

We show through numerical modeling that the range resolution of a multi-band, sparse frequency CW-LFM chirped signal has an effective bandwidth related to the modulation bandwidth and the band frequency offsets of all bands. The range resolution predicted from the effective bandwidth of our sparse CW-LFM signal is comparable to that of standard continuous bandwidth CW-LFM signals. We also discuss unique issues that arise from the use of sparse frequency CWLFM chirped signals, such as ambiguity and peak to side-lobe ratio fluctuations, and how they are related to the multiple frequency components of the signal.
