<br />2.3 Radar Data <br /> <br />Full volume scans of the Skywater 5 cm wavelength, narrow-beam <br />digital radar were collected every 5 min during periods having radar <br />echoes of interest. The radar was located 10 km north of Big Spring <br />at 32.30 N., 101.44 W., elevation 784 m MSL (Fig. 2.1). Radar charac- <br />teristics are described in Table 2.1. <br /> <br />Table 2.1. - Characteristics of HIPLEX SWR-75 radar 1/ <br /> <br />Peak transmitting power <br />Pul se duration <br />Antenn a type <br />Horizontal half-power beam width <br />Vertical half-power beam width <br />Effective system gain <br />Wavelength <br />Pulse repetition frequency <br />Receiver noise <br />Receiver <br />Receiver band width <br />Receiver dynamic range <br />System noise <br /> <br />250 kW <br />2.0111S <br />Circular parabolic <br />0.90 <br />1.00 <br />43. 7 2/ dB <br />5.4 cm <br />207/414 pIs <br />2 dB <br />logarithmic <br />0.6 MHz <br />80 dB <br /><3 dB <br /> <br />1/ After Schroeder and Klazura, 1978. <br />2/ This figure incorporates all wave guide mismatch and <br />similar losses beyond the directional couples as well <br />as random loss. <br /> <br />All digital radar tapes which had echoes of interest on HIPLEX <br />operational days were processed at the University of North Dakota (UND) <br />using detailed error-checking routines described by Schroeder and <br /> <br />Klazura (1978) and Brady et ale (1980). This set of programs auto- <br />matically checked for bad data and flagged those records for manual <br /> <br />review. Final radar archive tapes were then sent to the Bureau for <br /> <br />entry in the Skywater EDN. <br /> <br />35 <br />
