The laser beam of laser pointer is stable enough

The laser beam of laser pointer is stable enough. Laser radar and aircraft avionics systems, displays, user interfaces interface. 1995 C-141 aircraft with the first wind lidar flight test, followed by C-130 aircraft on the second and third test flight laser radar. Allegedly, operational use laser radar hardware needs to be small, can improve the accuracy of air-dropped more than 2 times. Gusts to ease the current system to the aircraft fuselage mounted accelerometer-based, performance is limited. Effective system requires aircraft turbulence encounters with turbulence before the measurement. Lidar turbulent gusts ability for future military and civilian aircraft to provide better gusts to ease system. U.S. Space Agency's "advanced flight measurement of airborne coherent laser radar", is exploring the concept.  According to the plan, to improve the ability of stronger laser radar seeker, in 1998 there will be sheltered under the conditions of bait and target identification. To address the role of laser radar seeker range is limited and the lack of all-weather capability, Wright Laboratory and diode laser and detector array in accordance with development plans, the development of high-power diode-pumped solid-state laser technology and the end of pulse detection laser radar imaging .
Laser radar developed by the laboratory, using the operating wavelength of 830nm 30W GaAlAs semiconductor laser, and images obtained from the response shows that the theoretical range resolution of 0.25m. According to sub-munitions guidance program, the Air Force Wright Laboratory has developed two types of submunitions used for laser radar seeker, which uses 24 yuan GaAs semiconductor laser array, the effective distance 200m laser radar, and the use of diode-pumped Nd (YLF lasers, 2km effective range of the laser radar according to the Air Force - Army combined anti-armor submunition's low-cost plan, Wright Laboratory has also developed the use of diode-pumped Nd (YVO4 laser laser radar seeker, and the experiment proved that the self-guided laser radar capability. Allegedly, this seeker is affordability, and is expected to yield 10,000 to $ 12,000 when the cost of production.The only use of laser radar-guided missiles in service, is General Dynamics AGM-129A advanced cruise missiles. This stealth cruise missiles rely on inertial period in the middle of most of the flight guidance, but the last paragraph of the use of laser radar. Guided submunitions with a small, low-cost laser radar seeker, has been the concern of the U.S. military. Army and Air Force through high-quality anti-materiel submunition technology demonstration program, sub-munitions guidance program, low-cost anti-armor submunition plans a series of plans, the development of laser radar-guided sub-munitions.
