I dont understand. Are you saying that the HQ-17 must stop before using its search radar?
If that was true then the PLA would throw it straight to the garbage bin. Can you imagine an entire armoured column stopping every 10-20 seconds to allow the HQ17 to use its search radar?....
Since I dont believe that the PLA has kindergarden kids running it, I am on the side that the HQ-17 can use its radar, get targetting data and shoot while on the move
Actually, I was saying the opposite. That the new vehicle stopped, as shown in the animation, because it might have stability issues if operating the tall and heavy search radar in motion.
Some arguments as to why:
1, HQ17 uses a caterpillar vehicle, and caterpillars have historically been chosen for relatively heavier vehicles than those using wheels. I don't have the weight figure for HQ-17, but Tor-M1 weighs 34 metric tons. Only in the last decade have some very heavy wheeled IFV approached those weights (Boxer IFV)
2. HQ17 uses a what looks like a light reflector antenna, where much of the radar components (like REX, transmitters, signal processing) are within the hull
3. The new vehicle appears to use an AESA search radar.
AESA
antennas are inherently heavier than other radar type antennas, because they carry all the power amplifiers within the antenna and often much of the front-end signal processing hardware too.
