Techniques used at the Arecibo Observatory's giant radio telescope in the areas of planetary radar astronomy, passive radio astronomy, and radar studies of the ionosphere and neutral atmosphere are described. Pulse compression, range-Doppler processing, and digital decoding in planetary studies are examined. Spectral line observations and the use of computerized Fourier analysis in passive radio astronomy are reviewed. The investigation of scatter in ionospheric studies, including the determination of the frequency spectrum of the scattered signal, is described, as is the use of the code pulse technique for measuring electron density profiles.
