G01S0003220000 derived from different combinations of signals from separate aerials, e.g. comparing sum with difference 1
G01S0003240000 the separate aerials comprising one directional aerial and one non-directional aerial, e.g. combination of loop and open aerials producing a reversed cardioid directivity characteristic 1
G01S0003260000 the separate aerials having differently- oriented directivity characteristics 1
G01S0003280000 using amplitude comparison of signals derived simultaneously from receiving aerials or aerial systems having differently-oriented directivity characteristics 1
G01S0003300000 derived directly from separate directional systems 1
G01S0003320000 derived from different combinations of signals from separate aerials, e.g. comparing sum with difference 1
G01S0003340000 the separate aerials comprising one directional aerial and one non-directional aerial, e.g. combination of loop and open aerials producing a reversed cardioid directivity characteristic 1
G01S0003360000 the separate aerials having differently- oriented directivity characteristics 1
G01S0003380000 using adjustment of real or effective orientation of directivity characteristic of an aerial or an aerial system to give a desired condition of signal derived from that aerial or aerial system, e.g. to give a maximum or minimum signal (G01S0003160000, G01S0003280000 take precedence);; 1
G01S0003400000 adjusting orientation of a single directivity characteristic to produce maximum or minimum signal, e.g. rotatable loop aerial, equivalent goniometer system 1
G01S0003420000 the desired condition being maintained automatically 1
G01S0003440000 the adjustment being varied periodically or continuously until it is halted automatically when the desired condition is attained 1
G01S0003460000 using aerials spaced apart and measuring phase or time difference between signals therefrom, i.e. path-difference systems 1
G01S0003480000 the waves arriving at the aerials being continuous or intermittent and the phase difference of signals derived therefrom being measured 1
G01S0003500000 the waves arriving at the aerials being pulse modulated and the time difference of their arrival being measured 1
