In order to test and evaluate the performance of the composition of laser radar systems, modules and components, and the co-working efficiency of modules and components, a heterodyne laser radar imaging of electronic tracking devices loop simulation platform is established. The electronic tracking device is composed of simulative target scene library module, signal simulator module, intermediate frequency amplifier, data acquisition logistic control module, imaging and data analyze module. The main features of electronic tracking devices of heterodyne imaging ladar system include: testing the various components of the laser radar system performance indices; efficiency analysis of heterodyne laser radar systems, and providing advices to improve the efficiency of proposed system. The results show that electronic tracking device loop simulation platform can reproduce the working process of imaging laser radar, analyze the co-working efficiency of the various modules; assess the performance of laser radar devices, and provide practical analysis results based on specific application requirements which provides a reliable analytical tods to eveluate the performance of the modules and device of laser radar system.
