Research of coherent accumulation characteristics on high speed missile platform

The problem of high-speed missile platform with high acceleration leads to poor coherent accumulation effect, requiring acceleration compensation. Aiming at this problem, this paper researches the relationship between signal wavelength, accumulation time and acceleration, derives the acceleration formula from the Doppler frequency width, proposes the acceleration compensation method for a short time accumulation, using missile inertial navigation equipment to output acceleration value, and method for a long time accumulation, combining the inertial navigation data and Doppler width acceleration measurement. The simulation results verified the validity of these methods.
