BORESIGHTING THE TRACKING RADARS

The Target Tracking Radar operator is aligning the reticule on his telescope to the reticule on the MTR telescope. The identical procedure as outlined with photo AR-13 with the exception that the TTR is not rotated in azimuth or plunged in elevation. The telescope is mounted in its normal configuration. SP2 Mac Donald is observing a dial on the Azimuth Drive unit to insure that both the MTR & TTR have the same Azimuth readings. The Azimuth Drive Equipment Enclosure door is open. The protected compartment to the left of SP2 Mac Donald houses a Modulator tube, a bank of charging capacitors and a High Voltage Transformer whose output is 18,000 volts which is applied to the cathode of a magnetron. Elevation and Azimuth drive motors and high power servo amplifiers are enclosed here also.
