Abstract :
The OFDM communication signal is proposed for spread spectrum radar signal generation. A radar signal processing technique is developed to solve the Doppler ambiguity in the pulsed Doppler radar by exploiting the multicarrier structure of the OFDM and the random phase modulation on the carriers in a Doppler compensation scheme. The novel processing technique is analyzed in detail, through both analytical derivations and Monte Carlo simulations, to demonstrate the feasibility of using the OFDM modulation with random phase coding for radar signals.
