G01S3/802 - CPC Classification

Classification description:

Direction-finders for determining the direction from which infrasonic, sonic, ultrasonic, or electromagnetic waves, or particle emission, not having a directional significance, are being received using ultrasonic, sonic or infrasonic waves Systems for determining direction or deviation from predetermined direction

Sub-classes:

G01S3/8022 » {using the Doppler shift introduced by the relative motion between source and receiver} 25
G01S3/8025 » {Conical-scan beam systems using signals indicative of the deviation of the direction of reception from the scan axis} 1
G01S3/8027 » {By vectorial composition of signals received by plural, differently-oriented transducers} 8
G01S3/803 » using amplitude comparison of signals derived from receiving transducers or transducer systems having differently-oriented directivity characteristics 33
G01S3/805 » using adjustment of real or effective orientation of directivity characteristic of a transducer or transducer system to give a desired condition of signal derived from that transducer or transducer system, e.g. to give a maximum or minimum signal 23
G01S3/808 » using transducers spaced apart and measuring phase or time difference between signals therefrom, i.e. path-difference systems 116
G01S3/809 » Rotating or oscillating beam systems using continuous analysis of received signal for determining direction in the plane of rotation or oscillation or for determining deviation from a predetermined direction in such a plane 5
