Abstract :
High resolution of targets, fine quality of image, reduction the computation and the power consumption of transmitter signal are four elements of radar systems attracted considerable interest at the number searchers of SAR focusing systems. To get this need, different modulation have been developed and used to perfect the quality of image like Linear Frequency Modulation (LFM). In this paper, we investigate new radar waveforms that are used to improve the resolution of targets named Gaussian linear frequency modulation (GLFM). Preliminary simulations are performed and discussed.
