摘要
结合相位编码步进频率(PCSF)信号的特点,文中提出一种改进的步进频率信号模糊函数的形式;详细分析了由于目标的运动带来的目标距离像走动的原因,并通过仿真实验分析了经速度补偿后的信号所具有的距离和多普勒性能。值得一提的是,文中利用卷积定理处理信号模糊函数的形式,对其它任何信号都具有普遍的适用性。
An improved form of stepped frequency signal ambiguity function is presented combining characteristics of phase coded stepped frequency(PCSF) signal. Range migration of moving target and the reason are studied in detail. Range and Doppler performance of velocity compensated signal are analyzed through simulation experiments. Convolution theory used to process signal ambiguity function in the paper is also applicable to other signals.
