Coherent video modeling of pulsed Doppler radar seeker (PDRS) for the six degree of freedom (6-DOF) closed loop trajectory simulation is discussed, which provides an efficient tool to the design and evaluation of surface-to-air missile (SAM). The topics covered are waveforms consideration, radar antenna modelling, target scattering characteristics, receiver processing, signal processor design and filter mechanism in data processing. The augmented proportional navigation law is used to generate the acceleration demands, while the bank-to-turn control command to obtain the fin-angle demand and the 6-DOF missile motion solution can then be accomplished by using SAM's aerodynamic characteristics. A typical air defense warfare scenario is designed to validate coherent video modeling as well as the 6-DOF closed loop trajectory simulation. The electronic countermeasures are also taken into account. Results show that this PDRS coherent video model is accurate for 6-DOF trajectory simulation, and the closed loop simulation offers an effective and practical way to design parameters and evaluate performance of SAM.
