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.
