EVALUATION OF THE MASER-EQUIPPED RADAR SET AN/MPS-34 AND AREA PRECIPITATION MEASUREMENT INDICATOR.
Abstract
Difficulties encountered with the Area Precipitation Measurement Indicator (APMI) and progress in overcoming these problems are discussed briefly. The MASER-equipped MPS-34 radar was operated during August near Magdalena, New Mexico, and 49-3/4 hours of data were collected of which 18 hours were on MASER mode. Nearly 700 feet of radar film collected on 19 days of operations are available for analysis. The MASER operation was limited by the occasional lack of helium, and for a short period by trouble with the pump klystron circuits. An addition was made to the elevation control system to provide smoother scanning in the RHI mode and to permit the RHI mode to be photographed through the same indicator system as the PPI mode. Analysis of data collected during August in New Mexico was limited to unusual echoes which appeared as coherent targets up to 42 db below full gain without the MASER operating. The conclusion is that these targets were birds. (Author)
