Common solutions to sidelobe level reduction for frequency modulated waveforms result in an SNR loss. In this correspondence, we propose a novel method using pulse diversity to reduce the range sidelobes while avoiding SNR loss. The proposed approach is based on shaping the power spectrum of the summation of a train of constant-amplitude linearly frequency modulated pulses to resemble a Gaussian function. We present a numerical example demonstrating a drastic sidelobe level reduction. Importantly, our approach avoids any processing SNR loss.en621629journal article
