Title:
OBSERVATION DEVICE, OBSERVATION SYSTEM, AND OBSERVATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/202892
Kind Code:
A1
Abstract:
[Problem] To provide an observation device, an observation system, and an observation method with which it is possible to eliminate ground clatter and to suppress removal of required echoes such as precipitation echoes.
[Solution] An observation system 1 includes an acquiring unit 41 and a substituting unit 44. The acquiring unit 41 acquires echo data ED1, ED2 respectively including Doppler velocity information from radar devices 10, 20 installed in different positions. The substituting unit 44 substitutes the echo data at a velocity zero location, at which the Doppler velocity is zero or substantially zero, from among the echo data ED1 or ED2 acquired from one radar device 10 or 20 for the echo data at the velocity zero location from among the other echo data ED2 or ED1 acquired from the other radar device 20 or 10.
