Title: Azimuth evaluation device and azimuth evaluation method for radio emitting source
Inventor: WADA SATOSHI
IPC: G01S3/40
Filed: 2001-01-19
Abstract: PROBLEM TO BE SOLVED: To solve the problem in a conventional azimuth evaluation device for measuring the azimuth of a radio emitting source that a directivity pattern is disordered by the electric influence of a mounting parent body such as air plane, naval vessel, when mounted on the parent body, to increase the azimuth orientation error.
