Abstract
RF sensors acquire and store RF data in memory. One RF sensor generates a trigger signal when the RF sensor detects a feature of interest in its acquired RF data. The detecting RF sensor wirelessly transmits the trigger signal to the non-detecting RF sensor. The non-detecting RF sensor reads the appropriate RF data from its memory in response to receipt of the trigger signal. The non-detecting RF sensor accesses the appropriate RF data using a time of day when the trigger signal is received and a predetermined time offset.
Claims17
A method for synchronizing two geographically distributed RF sensors using a pair of triggering devices, the method comprising:
- acquiring and storing RF data;
- detecting a feature of interest in the acquired RF data;
- generating a trigger signal;
- wirelessly transmitting the trigger signal;
- wirelessly receiving the trigger signal;
- and
- reading stored RF data based on a time offset associated with a time difference between generating the trigger signal and receiving the trigger signal.
An RF sensor, comprising:
- an RF receiver section operable to receive a trigger signal;
- a clock;
- and
- an instrument section comprising a first memory operable to store acquired RF data and a processor operable to read RF data from the first memory using a predetermined time offset and a time of day generated by the clock.
A system, comprising:
- a first RF sensor operable to detect a feature of interest in acquired RF data and responsively generate and wirelessly transmit a trigger signal;
- and
- a second RF sensor operable to wirelessly receive the trigger signal and responsively read RF data from a memory using a predetermined time offset and a time of day generated by a clock.
