What maximum range can a bistatic system achieve?

• A. 500 linear feet
• B. 1,500 linear feet
• C. 2,500 linear feet
• D. 3,000 linear feet

Answer: (B)

Bistatic systems have the transmitter and receiver at separate locations, so the signal must travel from the transmitter to the target and then from the target to the receiver. That two-step path loses more energy than a system where transmitter and receiver are together, so the reliable detection range is shorter. For typical security equipment and layouts, the practical, dependable range of a bistatic setup is about 1,500 linear feet. Going further—toward 2,500 or 3,000 feet—causes the returned signal to fall below reliable levels across varying targets and conditions, making detection less dependable. So, the 1,500-foot range reflects the balance between adequate signal return and the two-path geometry of bistatic sensing.
