After the XMTR has completed its warm-up, what is the proper sequence to place the SENTINEL system into operation mode?

The correct sequence to place the SENTINEL system into operation mode is to first activate the antenna rotation (ANT ROT ON), followed by turning on the high voltage (HV ON), and finally activating the radar (RAD ON). This sequence is essential for several reasons.

Activating the antenna rotation first ensures that the antenna is positioned correctly and is ready to begin scanning the area. This is a critical initial step because the antenna needs to be moving to properly collect data and track targets effectively. If the radar is turned on before the antenna has started rotating, it may not be able to detect targets efficiently or may produce erroneous information.

Once the antenna is in motion, engaging the high voltage is necessary for the radar components to operate correctly. This step powers the radar transmitter, allowing it to start generating the required signals. Only after the high voltage is activated should the radar be turned on; this ensures that everything is properly set up before the system starts sending and receiving information.

By following this sequence—starting with the antenna rotation, then high voltage, and finally the radar—operators can maximize the effectiveness and reliability of the SENTINEL system during its operations.
