... Introduction: In the present work the morphometric parameters for 87 large martian craters [1](with diameters from 411 up to 110 kms) have been determined: depth of a crater, the relation of depth of a crater to diameter (/D), height of a rim ­ h, with the help of profiles constructed on the basis of supervision of space vehicle MGS [2].The comparison with similar morphometric parameters of large lunar craters also is fulfiled. ... 2000) Morphological Calague Of the Craters Of Mars. ...

Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...
