INS/GPS组合导航下机载PD雷达DPCA性能分析
Performance Analysis of DPCA Detection for Airborne PD Radar Using INS/GPS Integrated Navigation
摘要
Abstract
The velocity measurement error of inertial navigation system accumulates with the time,which degrades the performance of the motion compensation and DPCA.In this paper, INS/GPS integrated navigation system is proposed to measure the airplane velocity, which does good for DPCA when detecting the slow moving target.On the basis of modeling the radar echo and the INS/GPS integrated navigation system, the measurement accuracy of inertial navigation system and INS/GPS integrated navigation system are simulated and the detection performance of DPCA under different measurement accuracy is given according to the background of airborne PD radar.The simulation results demonstrate that the measurement accuracy is low when using the inertial navigation system to measure the airplane velocity and DPCA can not detect the slow moving target.The measurement accuracy is very high by using the INS/GPS integrated navigation system to measure the airplane velocity and DPCA can detect the slow moving target.关键词
