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.
