|DESCRIPTION:||Fixed Seacoast Artillery microwave radar.|
|USES:||Gives PPI indication for harbor control and detection of surface craft and low-flying planes. IFF RC-182 is used.|
|SCR-582 covers 360°. From a height of site of 100 to 125 feet, the reliable maximum range is about 20,000 yards and the most probable maximum range is about 35,000 yards. Occasionally, ranges up to the 90,000-yard limit of the range scale can be obtained. Minimum range is about 1000 yards. Azimuth accuracy is of the order of ± 2° depending somewhat on the range scale in use. the range accuracy may be considered ± 3 per cent of the range scale in use. The range scales are 10,000, 30,000, and 90,000 yards. Set should be sited not less than 30 feet above the surrounding terrain and at least 100 to 150 feet above sea level. Optimum height of site is between 150 and 500 feet. Site should not include within the arc of surveillance any obstructions which would come within 5 to 10 degrees of the antenna axis.|
|TRANSPORTABILITY:||Shipment includes spares and separate generator. Complete shipment is packed in 41 units, including power unit and power house. Largest package (power unit) is 5'9" x 6' x 5'11" and weighs 2060 lbs.|
|INSTALLATION:||Set normally is installed in existing harbor defense or group observation posts by Signal Corps personnel. No tower or buildings are furnished as part of the set, but power plant shelters are obtainable.|
|PERSONNEL:||SCR-582 requires one man to operate the set and another to plot the position of detected targets. These men relieve each other every thirty minutes. A power plant operator and maintenance man must be available. For 24-hour operation a chief of section, five operators, two power plant operators, and one maintenance man are required.|
|POWER:||Requires about 1.8 KW, 110 V, 60 cycles, single phase.|
