Product Name: Scout™ Low Probability of Intercept Surveillance System

Product Description

Manufactured by MSSC (a joint venture of DRS Communications Company, LLC and THALES Naval Nederland), the SCOUT™ radar is a truly Low Probability of Intercept (LPI) radar system designed for shipboard surveillance and navigation applications. While it has detection performance characteristics similar to the AN/BPS-16 or other navigation radars, the SCOUT™ radar uses a Frequency Modulated Continuous Wave (FMCW) transmit waveform that enables it to detect a target well before the target's ESM equipment can detect the SCOUT™.

The SCOUT™ is a Low Probability of Intercept (LPI) radar primarily due to the low peak power -- just 1 Watt -- sent into the antenna. By comparison, a pulsed radar requires around 25 kW peak power into the antenna. Furthermore, the FMCW radar can meet many mission requirements with as little as 1 mW power. Typically the SCOUT™ radar cannot be detected by electronic surveillance equipment or radar warning receivers at ranges greater than a few kilometers. Under the same conditions, a pulsed radar is detectable by these devices at ranges exceeding 50 km.

The following description of the MSSC SCOUT™ radar is for platforms other than submarines. The only difference for deployment on a submarine is an antenna that will withstand the submarine environment. The FMCW radar has been integrated with several displays and is currently offered with the user-friendly Pathfinder Mk2 display. This display provides a PPI display of radar returns, intruder warning, automatic detection and tracking, and status information associated with the radar. Ideally suited for surveillance and navigation, the FMCW radar provides multi-target tracking and displays track history, track vector, and closest point of approach computation for target intercept.
