Description

The information on the Processor page is offered in groups.

Operation: These boxes provide generic information related to the operating parameters.
Beamformer: These boxes provide information related to the beamforming process.
Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception. This is achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference while others experience destructive interference. Beamforming can be used at both the transmitting and receiving ends in order to achieve spatial selectivity. The improvement compared with omnidirectional reception/transmission is known as the directivity of the array.
Beamforming can be used for radio or sound waves. It has found numerous applications in radar, sonar, seismology, wireless communications, radio astronomy, acoustics and biomedicine.

Operation

These boxes provide generic information related to the operating parameters.

Ping Count

: The Ping Count value is simply a consecutive count of transmissions ("pings") since the ST90 system was turned on and activated.

Ping Interval

The ping interval (1/ping repetition frequency (PRF)) is the ping rate measured in time between each acoustic transmission.

The phrase ping rate is used to describe the parameter that controls how often the ST90 system can or shall transmit acoustic energy (a "ping") into the water. The ping rate is normally limited by the maximum range settings. It also depends on hardware limitations. This may be, for example, how fast your ST90 system can handle the information from each ping, how fast it communicates with external peripherals, or how long time it uses to save data.
