Micro-Doppler effect testing technique for attitude of projectile in space flight

To measure projectile attitude in space flight, based on continuous wave (CW) radar, a new micro-Doppler effect testing technique is developed in this paper.It also establishes radar testing model for attitude of flying projectile and resolve micro-Doppler effect of projectile motion attitude. By distinguishing and geting attitude parameters such as micro-motion period, this technique can intuitively estimate the flight stability of projectile, and the validity of this technique is proved according to flight tests.
