A novel UHF radar system design for river dynamics monitoring
نویسندگان
چکیده
This paper proposes a novel ultra high frequency (UHF) radar system for river dynamics parameters monitoring. As compared with conventional radar system: (1) Intermediate frequency (IF) sampling mode of traditional superheterodyne receivers is replaced by the direct radio frequency (RF) band-pass sampling and orthogonal demodulation (2) Multi-channel antenna system is divided into two units, which realizes that one radar system operation obtains two-dimensional current vectors. Results of field test compared with EKZ-I current measurement at Xiantao Hydrological Station, China from August to September in 2014 are given to demonstrate the correctness and effectiveness of this system.

Extended Uhf Radar Observations of River Flow Velocity and Comparisons with In-situ Measurements
A RiverSonde radar system, operating at a frequency of approximately 350 MHz in the ultrahigh frequency (UHF) band, was installed on the Cowlitz River at Castle Rock, Washington, USA during October 2003 and has been operating for several months. Using techniques and equipment developed over several decades for measuring ocean surface currents at much lower frequencies, this radar system continu...
متن کاملMultimode/Multifrequency Low Frequency Airborne Radar Design
This work deals with the design of multimode/multifrequency airborne radar suitable for imaging and subsurface sounding. The system operates at relatively low frequencies in the band ranging from VHF to UHF. It is able to work in two different modalities: (i) nadir-looking sounder in the VHF band (163MHz) and (ii) side-looking imager (SAR) in the UHF band with two channels at 450MHz and 860MHz....

متن کاملDesign of a Novel Framework to Control Nonlinear Affine Systems Based on Fast Terminal Sliding-Mode Controller
In this paper, a novel approach for finite-time stabilization of uncertain affine systems is proposed. In the proposed approach, a fast terminal sliding mode (FTSM) controller is designed, based on the input-output feedback linearization of the nonlinear system with considering its internal dynamics. One of the main advantages of the proposed approach is that only the outputs and external state...
