Abstract: Frequency stepping technique is used in radar to achieve high range resolution and this technique requires inexpensive transmitter hardware. However, its matched filter output introduces undesired peaks known as grating lobes. In this letter efficient particle swarm optimization (PSO) based technique is proposed which judiciously determines the parameters of a linear frequency modulated (LFM) pulse train that enables effective suppression of grating lobes. Simulation results have been provided to demonstrate the efficacy of the proposed method. � 2014 Published by Elsevier Masson SAS.
