CLUTTER (WEATHER) REDUCTION STUDY.
Abstract
The study provides information of the wind, rainfall, and cloud moisture conditions which could reasonably be expected in areas of Ground Control Approach (GCA) operation. In conjunction with this information, the effects on microwave signals at S-, C-, and X-band are determined. The basic physical description of scattering due to hydrometers is reviewed and equations are presented for calculating attenuation and back-scatter cross sections. Profile plots covering many specific weather situations are provided. These are specifically designed for use in radar applications. Specific GCA type application of this information is provided for several realistic situations. It is found that the magnitude of the clutter return can be sufficient to mask an aircraft at ranges greater than a few kilometers. Methods of clutter reduction and applications of GCA radars to provide real time weather information for flight safety are discussed. Recommendations are made for study of the weather clutter frequency spectrums to provide needed clutter filter design criteria. (Author)
