Abstract
A method and arrangement for processing signals emitted by a plurality of apparent emitters that is detected by an Electronic Measures System/Direction Finder unit (ESM1). The ESM1 unit is adapted to identify a real emitter and at least one false emitter among said apparent emitters, based on the variance of emitter characterizing parameters for each apparent emitter. When false and real emitters have been identified, this information may be used to suppress clutter from false emitters, and/or to determine the position of the real emitter using observations from only one ESM/DF unit.
Claims14
A computer-implemented method for identifying real and false emitters observed by an Electronic Measures System, wherein said real and false emitters are identified by pulse processing the received signals, de-interleaving the signals, emitter processing the signals determining emitter characterizing parameters for each apparent emitter, the method comprising the steps of:
- determining, using a processing unit, the variance of each emitter characterizing parameter;
- selecting, using the processing unit, those apparent emitters originating from the real emitter into a group;
- sorting, using the processing unit, the apparent emitters according to the variance of the emitter characterizing parameters;
- and
- identifying, using the processing unit, the apparent emitter with the least variance values as the real emitter, and the other apparent emitters in the group as false emitters.
An apparatus for identifying real and false emitters observed by an Electronic Measures System, the Electronic Measures System (ESMi), comprising:
- a plurality of receiving antennas each with an individual receiving channel;
- and
- a processing unit wherein the processing unit is configured to pulse process, de-interleave and emitter process signals determining emitter characterizing parameters for each apparent emitter;
- said processing unit further including means configured to determine the variance of each emitter characterizing parameter, means configured to select those apparent emitters originating from the real emitter into a group, means configured to sort the apparent emitters according to the variance of the emitter characterizing parameters, and means configured to identify the apparent emitter with the least variance values as the real emitter, and the other apparent emitters in the group as false emitters.
