The received radar video signal, transmission timing signal, and antenna rotation signal

are sent to the display system. The radar video signal is a non-processed, log-compressed

signal. The antenna rotation signal is an incremental signal, and 2048 rotation pulses and

reference bearing pulses per cycle are used.

When a specified time has passed during the stopping of the communication signal from

the display system, the interface circuit moves into the protection mode, and forcibly stops

the transmission and the scanner unit.
