Abstract
Frequency-division multiplexing(FDM) has the advantage of transmission signals that can be separated without interference for multiple-input and multiple-output(MIMO) radar processing. However, we propose the use of code division multiplexing because the additional phase terms from the frequency gap for signal separation affect the angle estimation performance. We assume that the monostatic MIMO radar uses an orthogonal frequency-division multiplexing waveform for a vehicle and propose assigning one chip for each sub-carrier. In our simulations, we present a range-Doppler map result and comparison with the root mean square error for angle estimation.
