A Pulse Compression Waveform for Improved-Sensitivity Weather Radar Observations
The progression of phased array weather observations, research, and planning over the past decade has led to significant advances in development efforts for future weather radar technologies. However, numerous challenges still remain for large-scale deployment. The eventual goal for phased array weather radar technology includes the use of active arrays, where each element would have its own tr...
متن کاملHigh Resolution Weather Radar through Pulse Compression
In order to evaluate pulse compression for use in phased array weather radar systems, modifications to the Time-Series Weather Radar Simulator have been made which incorporate phase-coding into its functionality. This allows for evaluating the performance of various pulse compression schemes under controlled conditions. Barker-coded pulses with matched and mismatched filters were examined in re...
متن کاملPulse compression for weather radars
Wideband waveform techniques, such as pulse compression, allow for accurate weather radar measurements in a short data acquisition time. However, for extended targets such as precipitation systems, range sidelobes mask and corrupt observations of weak phenomena occurring near areas of strong echoes. Therefore, sidelobe suppression is extremely important in precisely determining the echo scatter...
متن کاملExtending the Radar Dynamic Range using Adaptive Pulse Compression
The matched filter in the radar receiver is only adapted to the transmitted signal version and its output will be wasted due to non-matching with the received signal from the environment. The sidelobes amplitude of the matched filter output in pulse compression radars are dependent on the transmitted coded waveforms that extended as much as the length of the code on both sides of the target loc...
متن کاملChapter 10 Pulse Compression Radar
10.1 INTRODUCTION Pulse compression involves the transmission of a long coded pulse and the processing of the received echo to obtain a relatively narrow pulse. The increased detection capability of a long-pulse radar system is achieved while retaining the range resolution capability of a narrow-pulse system. Several advantages are obtained. Transmission of long pulses permits a more efficient ...
