Analyzing the Target Recognition Capability of an Ultra-Wideband Radar System using Time-Frequency Algorithms

Ultra-wideband (UWB) pulse radar can provide high target resolution by using very short pulse durations. In the presence of heavy noise and interference of several pulses, the pulse-detection capability will degrade. Due to the transient behavior of UWB pulses, joint time-frequency algorithms can be used to achieve satisfying target resolutions. In this contribution, the de-noising and target resolution capabilities of various time-frequency representations are analyzed by simulations and measurements.
