Activity Detection Unit

DG009-M1 - Teledyne Defence & Space

Many advanced EW receivers, particularly those associated with ECM jamming systems, do not require the high resolution frequency information associated with a DFD or IFM based receiver. This is typically the case where a single pulse present within a broad frequency band is required to be detected and instantaneously down-converted to an IF band.

TDS manufactures a range of Frequency Activity Detectors (FADs) also known as Activity Detection Units (ADU) which perform frequency measurement of an RF pulse and output data in as little as 15ns. The basis of these products is TDS’s ability to produce high performance broadband channelisers and integrated detectors. These devices are ideal for receivers which must operate in very high pulse density environments.
