notes"This system is not a radar but is a sound-ranging system with the same purpose as counter-battery radar. Sound ranging system (Soras) 6 is a fully automated, EMP-protected, completely passive sound ranging system capable of accurately locating enemy gun positions. The system is not susceptible to jamming. The system is comprised of a computer terminal, nine microphones, and a meteorological unit. Each microphone is surveyed into position and acoustically designates an azimuth to each firer. The computer terminal then calculates intersection points with the azimuths for target locations. The system operates in temperatures ranging from -40° to +55° c. Normally, it takes between 2 and 45 seconds for the computer terminal to calculate target coordinates. But, the target coordinate calculation time depends on the number of sound sources within the same interval of time. Nine microphones are deployed in an area 8 km wide and 1-2 km deep. The microphone positions are determined by conventional surveying methods or by special equipment. An alarm on the calculator is automatically triggered if contact is broken with any of the microphones. The meteorological unit provides air temperature, wind speed, and wind direction. Two people can connect the meteorological unit and raise the mast in 15 to 20 minutes. The system possesses the ability to detect firing systems by itself and/or act as a passive cueing system when used in conjunction with an artillery location radar. There are no associated vehicles for the Soras 6 however, the Mercedes Benz Unimog U1350L truck (described within the table) provides a representative worldwide transportation capability for the system."
