Embodiment Construction
[0107] The RAV-Jerk model-based maneuvering target tracking method of the present invention will be described in detail below in conjunction with the accompanying drawings. (Refer to the attached figure 1 ).
[0108] Embodiment condition: assume radar wavelength λ=8mm, radar pulse accumulation time T=10ms, radar signal processing sampling interval T s =5×10 -5 seconds, target initial state: X(0)=[120000m,-426m / s,0m / s 2 ,2000m,0m / s,0m / s 2 ] T , the target movement process lasted 90s, and the maneuvering moment and acceleration are shown in Table 1. The sampling interval of radar data processing is distance measurement error Angle measurement error Radial Velocity Measurement Error Radial Acceleration Measurement Error Carrying out 100 Monte Carlo simulations, the root mean square error is: in is the estimated value obtained by each simulation, and d is the real value.
