Summary:
We already developed a bistatic frequency modulated continuous wave (FM-CW) radar. And we observed clouds using the radar on a ship "MIRAI" that is a Japanese scientific research vessel, in the Arctic Ocean and the Pacific Ocean. The radar provided good and sensitive data in these long-term observations. To improve the sensitivity of the radar more, we start to develop a prototype of Monostatic FM-CW radar. The monostatic radar has advantage rather than the bistatic radar, because it doesn't have parallax, it can be realized in half of the size, and more. Therefore, it is able to use larger antenna, and to change the direction of the antenna easily. In future, it expected that the radar is able to scan the whole sky. The prototype radar is isolated between transmitting part and receiving part using a circulator. There is cancel system to cancel leakage power to receiving side from transmitting side. As a result of the initial observation, clouds and rainfall were not observed because leakage power was still strong than reflection from clouds and rainfall. By doing more alignment and improvement, it anticipates that clouds and rainfall are observed in the high-sensitivity.
