Research on detection algorithm of high-speed and low-observable targets

Both ballistic missiles in midcourse trajectory and space debris have the characteristics of small RCS and high speed, which would be difficult to be detected by the warning radar system. In this paper, based on analyzing the influence of the velocity on high-speed and low-observable target´s detection, Keystone Transformation technique is presented to correct the influence of velocity. Finally, according to the system parameters of Cobra Dane radar, simulation is implemented to verify the coherent accumulation based on Keystone Transformation, whose performance is also compared with the coherent accumulation based on Envelope Alignment.
