Antenna and Feeder Systems of P-band Meteorological Radar

A new approach for designing antenna and feeder systems of meteorological radar which is inexpensive, fast scanning, dual polarization and phased array is proposed. This goal has been accomplished by a new technique, based on a special series and parallel feed network, to realize the scanning pattern with high gain and low side-lobe level. In this technique, the number of antenna elements, which can satisfy performances of radar, is significantly decreased to 2/3 of original scope. As a proof, a P-band tropospheric wind profiler radar, which has a 169¬element array and 13 feed networks with 30dB gain and - 30dB low side-lobe level, is presented. The simulation and measured results are presented, and performances are excellent.
