Abstract

In our previous work, we have shown that the channel equalization blocks of telecommunication systems can be used to sense the environment, a scheme which we call communication-based sensing (CommSense). The current work presents the ambiguity function analysis for different waveform in passive forward-looking radar geometry for CommSense system. Cramér-Rao lower bound (CRLB) for a two path receive signal model is also calculated for the time delay in the scattered path when there is direct path interference.
