APPARATUS AND METHOD FOR DETERMINING SIGNAL QUALITY IN A GEOLOCATION SYSTEM
First Claim
1. In a geolocation system for determining a geolocation of a target emitter, a method for determining the geolocation comprising:
- receiving a signal transmitted from the target emitter at each one of a plurality of sensors;
determining whether signals received at n sensors, from among the plurality of sensors, satisfy one or more threshold values related to a condition of the received signals;
if signals received at n sensors satisfy the threshold value, commanding m of the n sensors to transmit one or both of the signal received thereat or information related to the signal received thereat to a processor;
at the processor, determining time difference estimates for the m received signals; and
determining the geolocation of the target emitter from the time difference estimates.

In a geolocation system for determining a geolocation of a target emitter, a method for determining the geolocation. The method comprises receiving a signal transmitted from the target emitter at each one of a plurality of sensors; determining whether signals received at n sensors, from among the plurality of sensors, satisfy one or more threshold values related to a condition of the received signals; if signals received at n sensors satisfy the threshold value, commanding m of the n sensors to transmit the signal received thereat or information related to the signal received thereat to a processor; at the processor, determining time difference estimates for the m received signals and determining the geolocation of the target emitter from the time difference estimates.
