Abstract :
Presented is a novel extended correlation method to suppress the grating lobes of the high-resolution range profiles (HRRP) synthesised via the stepped frequency train of LFM pulses (SFT-LFM). By uniformly spacing the nulls of the envelope term to nullify the grating lobes, the method may effectively improve the sidelobe behaviour of SFT-LFM HRRP without loss of the range resolution. Numerical experiments illustrate the effectiveness of the method.
