Abstract
WE have recently measured the microwave brightness temperature over the lunar disk using a new 1.5 m aperture Cassegrain telescope with both cooled indium antimonide and Golay cell detectors. The measurements cover a fairly broad band centred at 1.5 mm and with a mean wave-length deviation of about 0.2 mm1. The results of solar scans show that the angular response function of the telescope when used with either detector is of approximately Gaussian form. The results of two series of lunar drift curve measurements are shown in isothermal form in Figs. 1 and 2. The results have been corrected for the time constant of the detector circuit but not for the angular response function of the telescope.
