The New Precision Radar that the Institute of Space and Astronautical Science（ISAS） developed for the tracking of the scientific-satellite launcher and sounding rockets is described. The radar has been operating since 1996 at the Kagoshima Space Center（KSC）of ISAS, of which operations conducted include trackings of three M-V rockets and numbers of sounding rockets. The key features of the New Precision Radar are（1）a 7m diameter antenna and（2）complete digital processing of the signals at IF and the after-stages. The margin of the signal detection in the secondary radar mode（beacon mode）has been improved 10 decibels from that of the old Precision Radar which ISAS had been using for long years. In the primary radar mode（skin mode）, the pulse compression with a compression ratio of 1000 has been achieved by digital techniques, and the maximum detection range has substantially been expanded.
