The present investigation is concerned with the start of a more systematic study of coherent E region echoes at high latitudes. A specific aim of the investigation is related to the simulation of coherent radar spectra of Farley-Buneman waves. A 'linear' theory of scattered power is discussed, and applications to radar power spectra simulations are considered. The assumption is made that the observed Farley-Buneman waves are in a linear growth phase during most of the time of their existence. This assumption, however, cannot apply to irregularities produced as a result of classical wave-wave coupling. It is, therefore, presumed that for the 1-m-type wavelengths discussed the waves are strongly excited by persistent currents and are generally not the product of wave-wave coupling. Attention is given to height variations, line-of-sight variations, electric field variations, distortions due to altitude convolution effects, and electron temperature effects.
