Novel Catalyst fro CH4-CO Conversion

Not Available Modern low probability of intercept (LPI) radars utilize large time-bandwidth product pulse compression waveforms, such as linear or non-linear frequency modulation (FM) and binary- or multi-phase coded signals, in order to reduce the peak transmitted power. These radars, example of which are Philips/Signaal's PILOT and Signaal's SCOUT coastal surveillance radars, pose a challenge to conventional EW support (EWS) receivers, which will typically detect the radar signal at ranges shorter than the radar detection range. This negative detection margin makes naval vessels such as submarines vulnerable to attack, since the radar can detect the periscope, other masts, or the sail, before the radar signal is detected and jammed. Technology Service Corporation (TSC) has investigated and developed a variety of LPI waveforms, as well as specialized feature detectors designed to intercept them. During Phase I of the present study, TSC proposes to investigate the feasibility of applying a variety of feature detection techniques, designed to detect the presence of a number of LPI waveforms, to an EWS receiver design concept that is built around a fast digital processor. In the Phase I Option, TSC will design a proof-of-concept EWS receiver, and develop a test plan to demonstrate the concept in Phase II.
