Abstract
"Modern low-probability of intercept (LPI) signals, such as spread spectrum frequency hopping and direct sequence coded waveforms (FHSS/DSSS), typified by wireless cell phone, IEEE 802.11, and Bluetooth signals, pose a serious challenge to conventionalsignal interceptors. Since Special Operations Forces (SOF) must continuously monitor such signals in a variety of tactical situations worldwide, novel new techniques are required to detect and identify such signals. TSC developed the concept of aDelay-Multiply Detector (DMD) interceptor, which it will adopt to the spread spectrum communications signal detection/identification problem. The DMD interceptor acts on digital data provided by a Digital Receiver Technology (DRT) family receiver,compliant with JTWS/JCAF requirements.During Phase I TSC, with the aid of SwRI, will survey the characteristics of FHSS and DSSS as well as other threat wideband signals employed worldwide, identify appropriate parameters for the DMD interceptor, and demonstrate its feasibility. Usingsimulation tools, we will estimate the interceptor's detection and identification performance, and design a preliminary Phase II demonstration test approach. Our goal is to fabricate the DMD interceptor in Phase II in C-PCI format, supplemented withpost-processing algorithms resident in the receiver's host computer. Fitting the processing in a PCMCIA format will require subsequent miniaturizations efforts. It is antic
