CW alternatives to the coherent pulse train—signals and processors

Research output: Contribution to journalArticlepeer-review

Abstract

We discuss CW signals, phase modulated by a periodic waveform, and their corresponding receivers. The combined response in delay and Doppler is almost identical to the (Ideal) response of the coherent pulse train. The receivers are matched to an integral number N of modulation periods of the transmitted signal. CW Implies a duty cycle of 100%. However, the signal duration need not be longer than N + 2 periods. The CW signals have the advantage that their peak power is equal to the average power. Their disadvantage is a more complicated receiver processing and the need for two antennas.
