Modeling and processing strategies of ultra-high speed moving target echo in near space

In recent years, near space has been a new research hotpot in the military field. Near space ultra-high speed moving target is a new case for radar target detection. This paper tries to establish the echo model of the ultra-high speed moving target and analyze its effect on the conventional processing of pulse Doppler radar. According to the characteristics of the near space ultra-high speed moving target, the target detection strategies are also proposed. Simulation results show the relationship of coherent integration, the radial and tangential velocity of the target and the bandwidth of the transmitting signals.
