چکیده

In order to evaluate pulse compression for use in phased array weather radar systems, modifications to the TimeSeries 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. In this study, a 5-bit Barker code has been integrated into the TSWRS along with a matched filter to baseline functionality and performance with regard to Integrated Sidelobe Level (ISL). While showing the 5-fold increase in resolution, the results show that an average ISL of -4 dB is produced with this simple design.

High 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...

Extending 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...

A Time Series Weather Radar Simulator Based on High-Resolution Atmospheric Models

A three-dimensional radar simulator capable of generating simulated raw time series data for a weather radar has been designed and implemented. The characteristics of the radar signals (amplitude, phase) are derived from the atmospheric fields from a high-resolution numerical weather model, although actual measured fields could be used. A field of thousands of scatterers is populated within the...

Pulse 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...

Chapter 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 ...
