7.3.4 Signal processing
Signal processing is performed on the SPU board. The figure below shows the concept
of the processing sequence.
STC control done on the RFC board is performed on the basis of the control data from
the SPU board. The processing of Echo Average and Echo Trail requires ship’s
heading/speed data or own ship position data. The ARPA requires ship’s heading/speed
data at the minimum.
