Tracking radar for scientific satellite launch with long-pulse primary radar capability

摘要

A new precision measurement radar for launching rockets has been developed in ISAS. The channel margin has been improved about 10dB comparing the existing system by using a larger antenna and implementing digital signal processing on the receiver. The maximum radar range at skin-tracking mode has been extended by long pulse transmission and pulse compression technique. The system has already been used for tracking of the M-V rockets and others and shown the expected performance. In this paper we resort the system structure, the performance, and operational results of this radar.
