Novel radar signal models using nonlinear frequency modulation
Two new radar signal models using nonlinear frequency modulation are proposed and investigated with respect to enhancing the target's range estimation and reducing the sidelobe level. The performance of the proposed signal models is compared to the currently popular linear and nonlinear frequency modulation signal models. The Cramer Rao Lower Bound along with main lobe width and the peak to sidelobe ratio are used for comparing the signal models to show that better range accuracy and smaller sidelobes can be achieved with the proposed signal models.
