說明書
Next, in some embodiments, each of the interrogators 1402, 1404, 1406, and 1408 may: (1) determine an estimate of the distance between the interrogator and the target device from the mixed RF signal; and (2) provide the determined estimate to the master interrogator 1402 or other processor. In turn, the master interrogator 1402 or other processor may estimate the location of the target device from the received distance estimates. Alternatively, each of the interrogators 1404, 1406, and 1408 may not be configured to determine an estimate of the distance, but instead may provide information that can be used to make such a determination (e.g., the mixed RF signals, a sampled version of the mixed RF signals, etc.) to master interrogator 1402 or other processor. The master interrogator 1402 or other processor may then determine: (1) an estimate of the distance between each interrogator (both receive only and master interrogator) and the target device; and (2) determine the location of the target device based on these estimates.
