Title: Attitude controller of antenna on moving body
Inventor: HAYASHI TAKESHI
IPC: G01S3/04
Filed: 1990-11-06
Abstract: PURPOSE:To reduce the number of sensors, reduce an attitude controller mounting space and simplify attitude correcting calculation by providing azimuth driving means for driving an antenna for rotation in an azimuth direction, yaw angular velocity detecting means for detecting the yaw angular velocity of a moving body and integrating means. CONSTITUTION:The integrated value of the yaw angular velocity of integrating means 4 show the quantity of change in a yaw angle. Since yaw angle change quantity corresponding yaw angle change follow-up control means 4, namely, the integrating means 4 drive an antenna Ant for rotation via azimuth driving means 141, when a moving body changes a moving direction, the antenna Ant is rotated in an azimuth direction while interlocking therewith and the misalignment of an antenna attitude with respect to a radio source is automatically corrected. Therefore, when the antenna Ant is set to take an attitude which is directed to the radio source by issuing search instruction 1, attitude correction interlocking with a change in the moving direction of the moving body is performed. Since only a yaw angular velocity sensor 30 detects the behavior of the moving body which moves as above and correcting calculation is the integration of a yaw angular velocity and the transformation of an integrated value to a yaw angle change quantity, the number of sensors is reduced and the attitude correcting calculation is simplified.

Filed: 1989-11-21
Abstract: PURPOSE: To reduce hands-on work necessary for testing a circuit by receiving digital equivalent objects of an analog flushback signal and determining the change in amplitude and phase occurring at a discontinuous part. CONSTITUTION: A test signal goes into a user system along a metal loop 24, and when this test signal is transmitted to the user system, a part of the test signal is flushbacked to A/D converters 32 and 34 due to discontinuity in a line.
