EVALUATION OF OBJECT RELATIVE SPEED APPLYING COMPLEXPULSE WITH HYPERBOLIC FREQUENCY MODULATION
Doppler shift of the reflected wideband signal spectrum can’t be directly applied to estimate located object speed with the sufficient accuracy. For the accurate estimation we propose to use an impulse that consists of two pulses with hyperbolical modulation frequency: the first with an increasing frequency and the second with a decreasing frequency. We derive the formula that connects the complexpulse parameters with object relative speed. We proposean algorithmspeed estimation. The simulation results that confirm the possibility of achieving of high accuracy by the proposed method are given.
