The re-entry capsule tracking radar is considered based on the long-range detection experiment results of the small flight object. In the experiment, the object with the radar cross section of 0.159m2 could be detected up to 17.5 km. In the consideration based on the results, the possibility of the over 20 km detection is shown by achieving assumed output power, and the automatic tracking is examined to save the operation cost. By these considerations, the feasibility of the re-entry capsule tracking system as a shared/dual-use technology with commercial products is increased.
