摘要
文中讨论了运动目标环境下步进频率信号的波形设计和处理问题.基于多散射点目标模型,提出了相位补偿法来避免目标运动时由于距离模糊带来的"目标分裂"现象.此外,利用步进频率信号的特点,提出了一种正负调频斜率信号测速方法.计算机仿真结果验证了上述方法的有效性.
The design and processing of a step frequency signal for a moving target is discussed.Based on the mutiple scatter target model,the phase compensation method is advanced for avoiding the'target split' caused by range ambiguity under the moving target condition.Moreover,based on the property of a step frequency signal,a method is proposed to measure the target velocity by using the positive- negative frequency modulation slope signal.The efficiency of the mothods is confirmed by the simulation result.
