Abstract : he general theory of rdar reflection from planetary surfaces is descrbed. It is shown how the slope of the surface profile can be obtained from the autocorrelation function of the signal envelope. The theory is applied to lunar observations made at 440 mc, 151 mc, and 38.25 mc, and a value of 14 degrees is obtained for the rms slope. The spatal correlation function of the lunar surface is also computed from theAUTOCORRELATION FUNCTION OF THE SIGNAL, AND IS FOUND TO SHOW THE EXITENCE OF SURFACE IREGULARITIES HAVING A SCALE OF THE ORDER OF MAGNITNCTION OF THE SIGNAL SHOULD SUPPLEMENT THOSE OF THE ANGULAR POWER SPECTRUM.
