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.

Method and system for collecting information about a plurality of

A three-transducer SAW filter is disclosed that includes a central input transducer requiring only one-half of the interdigital fingers normally required by prior art three-transducer SAW filters. As a result, two input transducers may now be provided in the space normally occupied by one prior art input transducer. The only requirement is that each input transducer have an axis of symmetry about which surface waves are propogated symmetrically. Since each input transducer may have a different frequency response, a dual-passband SAW filter may now be provided in the space normally occupied by a single prior art SAW filter. Furthermore, a multi-passband SAW filter may be provided by arranging pairs of input transducers between three or more output transducers which are electrically coupled in parallel. In addition, the input and output connections of a multi-passband SAW filter may be interchanged such that an input signal, applied to the parallel connected output transducers is frequency sorted by the passbands of each of the input transducers.
