Abstract: Methods, systems, and apparatus for transmitting a first set of stepped-frequency CW signals having first signal parameters, where the first signal parameters includes a first bandwidth and a first step size between signal frequencies. Detecting reflections of the first set of transmitted CW signals. Identifying an indication of a potential target in a frequency range of the reflections of the first set of transmitted CW signals from the detected reflections of the first set of transmitted CW signals. Determining second signal parameters for a second set of stepped-frequency CW signals in response to identifying the indication of the potential target. The second signal parameters include a second bandwidth and a second step size between signal frequencies, and where the second signal parameters focus on the frequency range in which the indication of the potential target is identified. Transmitting the second set of CW signals.
