“…If (for the purposes of error estimate) the spectrum is assumed to be a narrow band gaussian function with a peak value of 3000° K per Hz and an effective bandwidth of 28 Hz, then the rms uncertainty in the sum [Eq. (5)] would be about 1000 °K. That is, the temperature (84,500 "K) can be compared with the statistical uncertainty of 1000°K, and an uncertainty due to additive noise of 70 °K.…”

During the fall of 1967, the M.I.T. Lincoln Laboratory Haystack radar was employed to study the scattering properties of the planet Venus at 3.8-cm wavelength. An increase in the transmitter power to 300kW CW and a reduction in the system noise temperature to 60°K provided a considerable improvement in the radar performance compared with that available for earlier measurements. The frequency power spectra of the echoes were determined by digital Fourier analysis of the received signals. The total power in each spectrum was computed to yield the value for the radar cross section of Venus. These average 1.75 percent of the projected area of the disk, in good agreement with a reanalysis of results obtained in 1966. The signal spectra have been averaged and employed to derive the angular scattering dependence P(
