Characteristics of lateralscan interferometer
Abstract
The performance of a correlational interferometer for study of radiocontrast formation of the surface of Earth and other planets is analyzed, considering that such an interferometer must be mounted on an aircraft or spacecraft with its fixedlength baseline parallel, at least approximately, to the vector of the course velocity. The geometrical relations for such an instrument, in effect a lateralscan interferometer performing aperture synthesis, are formulated in a cylindrical system of coordinates and a point source is assumed. Calculations yield the synthesization diagram representing the indeterminacy function as well as the accuracy in terms of resolution and sensitivity, with K = the square root of (2 pi lambda L)/1 (X  wavelength, L = baseline length, 1 = antenna aperture along given coordinate) as a parameter and taking into account the signaltonoise ratio.
