1. An apparatus for determining location information for a target, the apparatus comprising:

  • a signal generation module configured to generate 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;

    at least one transmit antenna configured to generate electromagnetic radiation corresponding to the cyclic transmit signal without up-conversion of the cyclic transmit signal;

    a down-conversion module configured to down-convert a plurality of return signals received from a corresponding plurality of return antennas with the cyclic transmit signal to provide a corresponding plurality of baseband signals;

    a magnitude and phase extraction module configured to receive the plurality of baseband signals and provide magnitude and phase information for each return signal as a function of range;

    a target location module configured to determine a location of a target from the magnitude and phase information.
