Description

Incomplete input data. – 11 p.Doppler radar provides nearly continuous velocity-time information on the projectile during the flight down range. For fixed radar heads, the data can extend for as long as the projectile remains in the beam; for tracking radar heads, the projectile can typically be tracked to just before impact. Analysis of Doppler radar provides a table of drag vs. Mach number, which can be read into a trajectory code, allowing the user to accurately model the trajectory of the projectile. In addition, various other flight parameters such as spin rate, tracer burn out, dynamic and structural stability can occasionally be extracted from radar data. Firing a group of projectiles with nearly identical mass properties and exterior shape yields information regarding the average and standard deviation of projectile in flight performance.
