本文对Arecibo S波段雷达对IRAS-Araki-Alcock 1983 d彗星的观测结果作了详细的分析和解释。非常高的信号强度用于精确确定圆偏振的两个正交方向上的回波频谱形状。窄带分量用于对核的大小、旋转、周期、反射率和粗糙度施加约束。对宽带分量的详细分析产生了对粒子云的空间范围、位置和质量以及组成粒子的有效尺寸的估计或界限。41篇参考文献。
A detailed analysis and interpretation of the Arecibo S-band radar observations of Comet IRAS-Araki-Alcock 1983d are presented. The very high signal strengths are used to make an accurate determination of the shape of the echo spectrum in the two orthogonal senses of circular polarization. The narrow-band component is used to place constraints on the size, rotation, period, reflectivity, and roughness of the nucleus. Detailed analysis of the broadband component yields estimates of, or bounds on, the spatial extent, position, and mass of the particle cloud, as well as the effective size of the constituent particles. 41 references.
