Detection and Parameter Estimation of Chirped Radar Signals

摘要

This work investigated the detection of pulses and extraction of modulation parameters from different types of time-limited chirp signals, as may be found in pulse- compression radar signals. The work is split into two parts. The first part examines the pulse detection problem, i.e., the detection of the pulse start/stop times. Such information can be used to determine the pulse width and repetition rate of the radar systems under investigation in an automated fashion. We compare the robustness of three TCF-based schemes and an envelope detection algorithm in noisy environments.
