In this article. we consider using time-of-arrival (TOA) measurements from a single moving receiver to locate a moving target at constant velocity that emits a periodic signal with unknown signal period. First. we give the TOA measurement model and deduce the Cram $\acute{\text{e}}$ r-Rao lower bounds (CRLB). https://www.duospiritalis.com/limited-deal-Radio-Birdman-Rock-Roll-Soldiers-T-Shirt-super-grab/
