Fig.8 show s the processing result of the double delay canceller.Compared w ith the single delay canceller，the responses of low-velocity targets w ere restrained more severely，but they still can be identified，w ith the response amplitude of high-velocity targets obviously increasing.To measure multi-target range information from Fig.8，w e utilize the Findpeaks function of M atlab to obtain the coordinate of every peak，and calculate the accurate range w ith the coordinate's location value.The range measurement results from M TI are listed in Tab.2.By comparison w ith actual target ranges，the errors caused by Doppler frequency shift are small，w hich are in the order of 10-4to 10-3.Also，the error magnitude is proportional to the moving velocity.
