摘要：

The University Corporation for Atmospheric Research (UCAR) is exploring options for an airborne weather observation radar system, called Airborne Phased Array Radar (APAR), that would employ four large C-band phased arrays. This study examines a notional array design that addresses key performance goals of: small transmit beam width, a provision for transmitting with a beam that is broadened or "spoiled" in elevation, and low two-way integrated sidelobe ratio. The specific techniques used-array tapering and thinning, with phase weight beam spoiling-are described in detail, and results are provided.
