摘要： Apparatus which permits near-field calibration of a doppler antenna in the laboratory avoiding the high costs and uncertainties of flight calibration is shown. The antenna and an associated transmitter are mounted over and very close to a scattering surface and means provided to effect relative motion between the antenna and the surface. In one embodiment the scattering surface is on an endless belt which is driven under the antenna and, in another, the antenna is placed on an arm and rotated over an annular trough containing granular material.
摘要翻译：显示了允许实验室中多普勒天线近场校准的装置，避免了飞行校准的高成本和不确定性。天线和相关联的发射器安装在散射表面上并且非常接近散射表面，并且被提供用于实现天线和表面之间的相对运动的装置。在一个实施例中，散射表面在环形带上，其被驱动在天线下方，并且在另一个实施例中，天线被放置在臂上并在包含颗粒材料的环形槽上旋转。

摘要： This invention relates to cross-correlation with automatic rotational alignment of images. The correlation spot is distinguished from the background illumination by rotation of the transparency out of the optimum alignment position, whereby the correlation spot disappears into the background illumination.

摘要： 1. A correlator for measuring the relative position of two objects by means of radiant energy comprising, AN OBJECT EMITTING RADIANT ENERGY, ANOTHER OBJECT CONSTITUTING A PLANAR REPLICA THEREOF POSITIONED AT A FIRST SELECTED DISTANCE FROM SAID OBJECT, A DETECTOR FOR DETECTING RADIATED ENERGY, SAID DETECTOR INCLUDING A PLANAR SENSING AREA POSITIONED AT A SECOND SELECTED DISTANCE FROM SAID REPLICA, SAID REPLICA BEING SMALLER THAN SAID OBJECT IN THE RATIO OF SAID SECOND DISTANCE TO THE SUM OF SAID FIRST AND SECOND DISTANCES, SAID REPLICA INCLUDING MEANS DIRECTING SAID EMITTED RADIANT ENERGY TOWARD SAID DETECTOR WHEREBY A CORRELATION PATTERN OF RADIATION INTENSITY IS APPLIED TO SAID PLANAR SENSING AREA, THE DISTANCE OF THE CENTER OF SAID CORRELATION PATTERN FROM THE CENTER OF THE PLANAR SENSING AREA BEING A MEASURE OF THE MISCORRELATION OF SAID REPLICA WITH SAID OBJECT.
