다국어 초록 (Multilingual Abstract)

In this paper, the velocity based hybrid doppler processing method is proposed to increase SIR. The proposed method uses two filters, MTI and FIR, for each velocity interval. The proposed algorithm uses a velocity boundary and two parameters are specified by Monte Carlo simulation that determine this value. The first is the ambiguity velocity which has a linear relationship with the velocity boundary. The second is the standard deviation of the FIR filter, and we investigate that it is logarithmic with the velocity boundary. Since the detection probability increases as the SIR increases, the detection performance improves as the SIR increases. Finally, the proposed algorithm was verified through simulation.
