Improved algorithm for generated radar image are presented in chaper 4 : 1 ) acipss is improved in radar echo generation . new method is to combine acipss with single back buffer display . the combination realize high level simulation of true antenna sweep effect 1 )采用扫描线求交回波生成算法和单后备缓存显示相结合的方法比较好地实现了雷达回波旋转扫描显示的高质量仿真,这将在第四章第一节中详细阐述。
