Abstract: A method for determining location information for a target may include generating a cyclic transmit signal having a fixed frequency slope over a substantial portion of each cycle and an operational frequency that is selected to penetrate foliage, transmitting the cyclic transmit signal without up-conversion with at least one transmit antenna, down-converting two or more return signals received from corresponding return antennas with the cyclic transmit signal to provide a corresponding set of baseband signals, extracting magnitude and phase information for each return signal as a function of range from the plurality of baseband signals, and determining a location of a target from the magnitude and phase information. A corresponding apparatus, system, and computer readable medium are also disclosed herein.
