Abstract:
Embodiments provided describe detections of RF leakage test signal emanating from cable plant. In one embodiment a single mobile receive antenna, connected to a complex demodulator mobile receiver, receives a stabilized test signal radiating from the cable plant. The test signal may be a known continuous wave (CW) carrier or other deterministic signal. The received test signal varies in phase as a function of a position of the mobile receive antenna relative to the location of a leakage antenna. The phase variance forms a Doppler shift as the test antenna moves relative to the leakage antenna. The receiver generates multiple in-phase (I) and quadrature (Q) test signal samples over a SPA (synthetic phased array) distance as the test antenna's travels, and the samples are inserted into a Fourier transform. The result of the transform is instantaneous Doppler frequency shift, from which a bearing angle can be computed.

Claim (Index 5):
A system for detecting one or more leakage antennas that receive a first transmitted test signal, comprising:\n a mobile transmit antenna connected to the first transmitted test signal transmitter for transmitting the first transmitted test signal; a stationary receiver and processing unit connected to the one or more leakage antennas for receiving and processing mobile transmit antenna generated signals and producing a first and second set of I and Q samples as a result of said processing; a location processing unit for determining the location of a first test antenna location and a second test antenna location; and a Fourier transformer processing unit for converting the first set of I and Q samples into a first set of Doppler frequency components associated with the first test antenna location and converting the second set of I and Q samples into a second set of Doppler frequency components associated with the second test antenna location; and a bearing angle processing unit configured to convert of first set of Doppler frequency components into first bearing angle associated with the first test antenna location and the second set of Doppler frequency components into a second bearing angle associated with the second test antenna location; wherein the location of the leakage antenna is determined as the locations where said first bearing angles from first test antenna location intersect said second bearing angles from second test antenna location.
