Abstract: This paper presents the developed step frequency model for high range resolution of target in radar system. The idea behind this research is to improve the detection capability of radar systems through improved step frequency model. This was achieved by transmitting a long linear frequency modulated (LFM) signals in a step-wise pattern, in which the centre frequency of the narrow bandwidth pulses of the transmitted signals are changed step by step and, are synthesized at the receiver to give a time profile characteristics of the target in view. The work was implemented using Matlab and the result of the simulation was carefully analyzed using the Ambiguity function for waveform analysis. It was observed that this waveform model really improved the range or detection index by 98% accuracy
