Radar Transmitter and Receiver Test with Ultra-Wideband Pulsed Signals
Application Notes
Ultra-wideband (UWB) technologies were originally designed for short-range connectivity at high data rates in applications such as gaming and video streaming. Today, UWB is being used in a growing range of applications such as high-precision anti-collision systems, mine detectors and asset trackers. Depending on the needs of the application, the UWB signal may be modulated with pulse or orthogonal frequency division multiplexing (OFDM) techniques.
This application brief focuses on a solution for testing of transmitters and receivers that use pulsed UWB signals. There are three major sections: the problem, the solution, and the results and benefits. The problem section covers the general and specific measurement challenges. The solution shown here is based on an actual test system designed to test transmitters and receivers in a pulsed UWB radar system. The results from this system provide significant benefits from technical and operational perspectives.
