VERTICAL CHARACTERISCTCS OF RAINFALL USING C-BAND MULTI PARAMETER DOPPLER RADAR (COBRA)

Effects of Radar Beam Shielding on Rainfall Estimation for the Polarimetric C-Band Radar

Radar reflectivity (Zh), differential reflectivity (Zdr), and specific differential phase (Kdp) measured from the operational, polarimetric weather radar located in Trappes, France, were used to examine the effects of radar beam shielding on rainfall estimation. The objective of this study is to investigate the degree of immunity of Kdp-based rainfall estimates to beam shielding for C-band rada...

Measuring Vertical Rainfall Velocity through Spaceborne Doppler Radar: Performance Analysis and System Requirements

In this paper we will present the results of the trade studies on the performances of a spacebome Doppler radar in measuring vertical rainfall velocity. Particular emphases will be placed on: 1) the choice of the PRF vs. antenna size ratio, 2) the choice of the observational strategy, 3) the choice of the operating frequency; and the 4) processing strategy. The results show that accuracies of 1...

Doppler Estimation Using a Coherent Ultrawide-Band Random Noise Radar

The University of Nebraska has developed an ultrawide-band (UWB) coherent random noise radar operating over the 1–2 GHz frequency range. The system achieves phase coherence by using heterodyne correlation of the received signal with a time-delayed frequency-shifted replica of the transmit waveform. Knowledge of the phase of the received signal and its time dependence due to target motion permit...

Fpga Based L - Band Pulse Doppler Radar

S-Band Doppler Wave Radar System

In this paper, a novel shore-based S-band microwave Doppler coherent wave radar (Microwave Ocean Remote SEnsor (MORSE)) is designed to improve wave measurements. Marine radars, which operate in the X band, have been widely used for ocean monitoring because of their low cost, small size and flexibility. However, because of the non-coherent measurements and strong absorption of X-band radio waves...
