Abstract
A Doppler estimator is designed for vehicular spread spectrum radar operating with the matched filter. Simulation results demonstrate that the estimated error of the relative speed between the leading car and the host car decreases with the relative speed. The maximum estimated error of the relative speed could be reduced to ±0.15 km/h within 0.84667 μs processing time
