Doppler location of signal leaks in an hfc network |
| 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). |
