Title:
DOPPLER LOCATION OF SIGNAL LEAKS IN AN HFC NETWORK
Document Type and Number:
WIPO Patent Application WO/2017/192206
Kind Code:
A3
Abstract:
Doppler shift is used to locate leaks in a network. Leaked signals include a component having a nominal frequency. The invention comprises: (a) moving along a route in the network; (b) recording a speed at a number of points; (c) at each point, receiving the component at a received frequency; (d) for each point, measuring received frequency; (e) for each point, determining a measured Doppler shift from received and nominal frequencies; (f) estimating a zero Doppler shift and a zero Doppler shift point based on the measured Doppler shifts; and (g) estimating leak location based on results in step (f).
