ITEM NAME: RADAR SET
TYPE: AN./MPQ-10, AN/MPQ-10A
Feed: Coaxial lines.
RELATION TO SIMILAR EQUIPMENT
Antenna Rotation: 3600 rpm (automatic tracing).
Beam Width: (Without Conical Scan)
The AN/MPQ-10A differs from the AN/MPQ-10 primarily in the
Azimuth: 5 deg at half-power
type of altitude computer system used. The AN/MPQ-10A
Elevation: 5 deg at half power
uses an electrical resolver-type altitude computer instead of
Transmitting System
the mechanical resolver computer used in the AN/MPQ-10.
Frequency Range: 2700 to 2860 mc
This difference does not affect the operating procedures of the
Wave Length: 10 cm (nom)
radar, but has required that several chassis be modified and 2
