Radar Technologies for SOF

The proposed effort addresses the threat warning receiver for the SOF through prototype design, development, fabrication, and experimental testing of a miniaturized receiver that: (1) has negligible emissions over a bandwidth of 3 to 40 GHz to precludedetection by an enemy receiver, (2) requires extremely low power to operate, (3) can be easily carried or worn and used by SOF, and (4) lends itself to covert operation. In addition, the development of algorithms that can execute the detection of threatemissions with little or no effort on the part of a SOF, except to turn a TWR on, is a major objective. In addition, RDAS' proposed architecture improves the mobility of the SOF because the size and weight of the TWR is minimized as well as keeping powerconsumption to a low level. The design philosophy for the proposed receiver is to receive the signals and down convert these signals to a frequency that is compatible with the current digital receiver and processor. This maximizes leveraging of thesubsystems that have been developed to date. Furthermore, this design will be consistent with the desired direction finding capabilities associated with other modules and for interfacing with a Body Worn Antenna.
