Abstract

In the application of aperture laser radar, in order to improve the range resolution of image, in general adopting linear modulation signal. But in practice, the transmitting signal of tunable laser is linear wavelength modulation. In order to make clear the effect of linearity of tunable laser to the quality of synthetic aperture laser radar’s image, the expression of linearity of linear wavelength modulation signal has been developed according to the definition of linearity and the effect of linear wavelength modulation signal to the quality of synthetic aperture laser radar’s image has been analyzed. The result shows that the same influence trend that with the pulse during time and coefficient of wavelength-modulated increase, the linearity increase and the quality of synthetic aperture laser radar’s image deteriorate and that the increasing carrier wavelength do the reverse. And further a step, the linearity and the quality of synthetic aperture laser radar’s image have been positive correlative, so the linearity deteriorates the range resolution of laser radar.
