China TianYing TY-LR74 military 15km~20km miniaturized laser rangefinder module designed for integration into compact airborne, maritime, and land based observation systems, provides accurate range performance to dynamic targets in extremely compact unit that weighs 550 g.
Depending on weather conditions and target characteristics, ranges between 200 m and 30 km can be measured, building 20km and drone 4.2km that have been proven. The measuring accuracy is 1m. Up to 50 measurements can be carried out in 25 seconds with a measurement frequency of 2 Hz.
The system is equipped with an external communication connector enabling remote operation and output of electronic ranging information for further processing and display.
15km~20km Laser Rangefinder of Application:
1) Airborne observation systems.
2) Border surveillance.
3) Border control systems.
4) Maritime surveillance systems.
5) Vehicle-mounted reconnaissance systems.
6) Land-based surveillance systems.
Question:
1, Why many 20km/30km/40km laser rangefinder can not measure tank 10km in standard 23.5km visibility?
Because their 20km/30km/40km is theory data or high reflection large target in ideal visibility condition, even reflection need beyond 80% and visibility need beyond 50km.
2, Why many NATO target 10% reflection 12km laser rangefinder can not measure tank 10km in standard 23.5km visibility?
Because their 10% reflection is not real performance data, 2.3m x 2.3m NATO taraget is not real tank, or their NATO target effective size is different..
3, Why many laser rangefinder is only show max measurement rate?
Because max rate and continuous rate technology demand is different, such as max 12.5Hz 10sec to 60 sec, maybe then 5Hz is max 1 min to 3 min with cycle.
4, Why many laser rangefinder price is very cheap?
Because performance is different, if used for same performance, then our price is very cheap. that is why many laser rangefinder do not show their main performance data.
