Abstract

The First Order Approximation technique is used in current generation of radars to compensate for the frequency shift due to the target's velocity. A common practice in radar systems to improve their resolution and performance is to increment the Time-Bandwidth (TBW) product of the transmitted signal. As the first order approximation is comprised of only the first two terms of a power series expansion; any significant increase in the TBW product of the signal results in significant errors in the radar image. In this research, the full Doppler compensation methodology was implemented and compared to the common approximation. The Time-Bandwidth Product was increased for a target moving at constant velocity, and the marched filter outputs were compared for each case. Qualitative and quantitative analysis of the results is presented.
