LINE SCAN YAW MEASUREMENT SYSTEM

The Line Scan Yaw Measurement System consists of an electronic line scan camera, camera/frame grabber interface board, and a personal computer. Specialized software allows the system to be used with any shell profile. Required inputs to the system consist of a pulse indicating when the round was fired and the actual muzzle velocity of the fired round.

Results are typically obtained within a minute following the firing, compared to hours using the older photographic streak camera methods. This permits immediate adjustments to gun settings to be made and allows for larger amounts of data to be collected in shorter periods of time, thereby greatly reducing the costs associated with field data collection.

The system was validated on the test firing range at Picatinny Arsenal, N.J. where the Yaw angle of projectiles traveling at 2,740 feet per second was successfully measured.
