Ultra-Wideband (UWB) Imaging Array Surveillance Sensor

The goal is to develop and demonstrate an UWB imaging surveillance sensor array capable of detecting intrusion of man or machine in to secure (exclusion) zones. The asynchronous nature of modern war exacerbates the protection needs of critical infrastructure: airfields, waterfronts, and other facilities. Developing a multi-lateral UWB sensor fence-line has immediate application for force and infrastructure protection both domestically and abroad Sperient proposes a multilateral time-of-flight impulse radio-radar system to enhance detection accuracy, eliminate false alarms, and operate on the lowest power with the stealthiest signal. The multi-lateral approach is superior to conventional sensors because scaling information about the target may be derived from multiple sensors. The approach includes utilizing Sperient’s (patent pending) impulse communication technology to detect time-of-flight (ToF). When a target passes between the radio transmitter and receiver, the difference in ToF is more reliably detected than in conventional systems. Radios used as described constitute an ultra-high resolution sensor. Additionally, detection range goes as 1/R2 rather than 1/R4-yielding much longer detection ranges. Since detection depends on time-of-flight (TOF) rather than amplitude, the sensors will yield better resolution and noise immunity. Lastly, multiple sensors enable better target estimation and may include: target size, gait, number of legs, and potentially heart and breathing rates.
