Ultra-Wideband Radar System Design - Integrating Design with Ultra-Wideband Test for Flexible Radar Verification

August 11, 2011

Ultra wideband (UWB) Radar has become increasingly popular in both commercial and defense industries. UWB Radars (whether impulse, LFM, noise, or OFDM-based) are defined as having a bandwidth of greater than 0.5 GHz, or more than 20% of their center frequency, and are regulated by FCC rules that allow UWB technology to coexist with existing radio services without causing interference. They offer several advantages, including high accuracy for target detection, good precision for penetrating radars, and low cost for combining radar and communication systems. UWB Radars can pass through walls and other obstacles for geolocation/positioning, and can support multipath immunity and frequency diversity with minimal hardware modifications.

Modern UWB Radar systems often operate in environments that are unpredictable, with interference, jamming and other “real world” performance limitations. Therefore, during system development, it is critical for engineers to understand how their actual hardware will perform in these environments.
