Two AN/TPQ-53 arrays operating in 360-degree modes should be separated by how many kilometers?

• A. 5 km
• B. 10 km
• C. 20 km
• D. 25 km

Answer: (C)

When two AN/TPQ-53 arrays operate in 360-degree mode, the goal is to avoid mutual RF interference while still providing overlapping coverage. Placing them 20 kilometers apart achieves that balance: it keeps their transmitters and receivers from saturating each other and from generating clutter that degrades performance, yet it’s close enough that their surveillance fields still complement one another for continuous situational awareness. Distances like 5 or 10 kilometers risk strong interference and clutter between the radars, while 25 kilometers tends to be more separation than needed for effective overlapping coverage. Therefore the recommended separation is 20 kilometers.
