Abstract

PURPOSE:To achieve a correct interpretation of data with an easy comparison of image data with an artificial satellite and a radar by receiving a transmitted wave from the same transmission source and an echo signal from the same zone with the artificial satellite and the radar. CONSTITUTION:As an artificial satellite 1 reaches almost right above an antenna 32 of a ground radar, a radar of the satellite is made to synchronize with the ground radar through an antenna 36 or the like of a tracking radar while a microwave is transmitted to the surface of the earth from an antenna 36 with the directivity matching the azimuth. An echo signal formed in the same zone on the surface of the earth is received with a radar of the satellite 1 while done with the antenna 32. Both image data based on the transmitted wave from the same transmission source and the echo signal from the same zone are compared easily thereby enabling an easy and accurate interpretation of data and a highly accurate correction of data.

Al branches can be expanded. If mounted on anti-air pirates, it will gain a considerable amount of attack power, so it can be expected to further expand its territory. In addition, if the ship's power is reduced, it is expected that the received power will be increased by installing a large device and using a large antenna and a low amplification gain. Moreover, by setting up a number of Ph.D. at the same time, data can be distributed over a wide range. Naturally, by using the data obtained by other methods such as excavating the ground, which is the target of observation survey, by using other methods such as buoys, etc. Interpretation can be more accurate.
