%X By transmitting wide band LFM pulse and using stretch method, high resolution range profile of target can be obtained, and the range of still object can be exactly measured. While, the ranging precision and the quality of range profile may be influenced by the velocity of the object. To overcome these shortcomings two-step stretch processing method can be used. Theoretic derivation and the simulation results, that shows that by using this method range estimation with high precision and velocity roughly estimation can be obtained, are presented. By using these estimation values, the range tracking, profile, status forecasting and MTI(Moving Target Indication) process can be realized.
