TARGET SPOTTING AND TRACKING APPARATUS AND METHOD

摘要

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.

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.
