Metric Calibration of the Millstone Hill L-Band Radar.

Abstract

The precision Lageos orbit is used for near real time calibration of the Millstone Hill Radar 1 MHz chirped frequency domain tracker. With independent tracking data, the range calibration is given to approx. 1 m, with Millstone data the range calibration is given to approx. 5 m. The range rate is unbiased measurement, with an accuracy of approx. 1 mm/sec. The azimuth and elevation are calibrated to 0.020 deg and 0.002 deg respectively. Tables of calibration constants are given. Keywords include: calibration; radar calibration; extended range calibration; laser ranging; Lageos; precision orbit determination; and refraction.
