Abstract Incoherent scatter radar is used to probe the ionized medium with characteristic parameters that vary by many orders of magnitude. In some circumstances simple radar techniques provide adequate or even optimum results; in others, special techniques are necessary. Two problems must be simultaneously solved. First, range ambiguity must be eliminated, and second, the statistical errors in the data must be kept to an acceptable level. We briefly state the theory of radar pulse compression since some of the complicated techniques are easily understood by analogy with pulse compression. We review the seven frequency long pulse technique used at Arecibo, and show that pulse compression theory is useful in simplifying the World Day experiment. The coded long pulse and alternating codes techniques are two recent developements which make optimum use of the transmitter power in many circumstances. These are discussed in detail and an analogy is developed between these techniques and those used in pulse compression.
