Abstract
A sensor performs input pulse deinterleaving based on an angle of arrival (AOA) of each sensed pulse. An AOA determination unit determines an AOA for each received pulse. The pulses are then sorted based on AOA into a number of AOA bins. The data within each bin is then analyzed to determine whether it corresponds to an emitter of interest. Bin data corresponding to emitters of interest are then transmitted to a remote processing facility for additional processing.
Claims19
A method for use in collecting information about a plurality of emitters, said method comprising the steps of:
- receiving electromagnetic pulses from a plurality of remote emitters at a first location;
- measuring, for each of said electromagnetic pulses, a relative position of a corresponding emitter with respect to said first location;
- sorting said electromagnetic pulses into a plurality of groups based on measured relative position information, each of said plurality of groups corresponding to a particular emitter within said plurality of remote emitters;
- analyzing electromagnetic pulses within each of said plurality of groups to identify a group corresponding to an emitter having a predetermined transmission characteristic;
- and
- transmitting data about the identified group to a remote processing station via a communication link between said first location and said remote processing station, wherein said remote processing station is operative for analyzing said data to derive additional information about the corresponding emitter.
In a system for collecting information on emitters of electromagnetic energy in a first region, a method for processing pulses received from said first region, said method comprising the steps of:
- receiving a first electromagnetic pulse from said first region at a first location;
- determining an angle-of-arrival (AOA) of said first electromagnetic pulse;
- and
- associating said first electromagnetic pulse with a first emitter in said first region based on said AOA;
- said step of associating includes transferring information relating to said first electromagnetic pulse to a memory location associated with said first emitter;
- analyzing data within said memory location to determine whether said first emitter is an emitter of interest;
- and
- transmitting data from said memory location to a remote processing facility when said first emitter is found to be an emitter of interest.
A system for collecting information about a plurality of emitters of electromagnetic energy in a first region, said system comprising:
- a sensor for sensing electromagnetic pulses transmitted by emitters in the first region, said sensor including an angle of arrival (AOA) determination unit for finding an AOA for each of the electromagnetic pulses, a plurality of AOA memory bins, and a sorter for sorting electromagnetic pulse information into the plurality of AOA memory bins based on AOA;
- a processing facility remote from said sensor for processing emitter data collected by said sensor;
- and
- a communication link between said sensor and said processing facility for use in transmitting electromagnetic pulse information stored within said plurality of AOA memory bins to said processing facility for further processing.
