Abstract

A maser preamplifier designed into an X-band weather radar set AN/ MPS-34 increased the radar's sensitivity by 12.5 dB to an over-all 118.5 dBm. Many low-performance, obsoleted sets could be converted to a high-performance system through the inclusion of a maser. A qualitative discussion of the maser's operation is presented, and the quantitative effects of the maser low noise temperature on the radar's overall noise figure is derived. The meteorological targets not previously detectable are analyzed, and anticipated target detection is forecast.
