The Student Led Test Bed (STB) is part of the NSF Engineering Research Center CASA and is currently focused in developing low-cost and low infrastructure radar networks to fill lower atmosphere gaps not covered by current technology. The first radar node, which is part of a small region radar network, will significantly improve the time and spatial resolution of the radar data measured for the lower...
This paper addresses the blind-zone problem associated with pulse compression techniques used to overcome the low peak power of solid-state transmitters, as well as interpulse coding techniques that take advantage of high duty cycles to mitigate range-velocity ambiguities. The implementation of these techniques on the CSU Wideband Experimental X-band (WiBEX) radar is presented.
Pulse compression is a useful technique for weather radar, as an enabling technology to facilitate use of low-power solid state transmitters. It also has the benefit of improving the dynamic range and range resolution of the radar, permitting rapid scanning of a volume. The nonlinear FMpulse waveform described produces the low sidelobe levels required for weather radar applications, while remaining...
Polarimetric variables are an essential part of algorithms for improved rainfall rate estimation, attenuation correction and hydrometeor identification. In such systems the transmit polarization state changes according to some fixed pattern that is repeated. The simultaneous mode and alternating mode waveforms are commonly used in weather radars. In the simultaneous mode of operation the horizontal...
