Can it be picked up by radar?

Information about an object in a distant location can be gathered by using a distance and direction radar.
For example, airport radars emit radio waves in a specific direction by using a parabolic antenna, which continuously rotates.
The direction of an aircraft can be told according to the direction in which the antenna was pointing when the reflected radio waves were received. Also, by measuring the amount of time from when the radio waves were transmitted until when the reflected waves were received, the distance to the aircraft can be calculated. The radar being researched at the Okinawa Subtropical Environment Remote-Sensing Center can calculate the distance and direction of typhoons and clouds in the same manner.
