     When an ideal STRETCH signal passes through a linear system and then the output signal is mixed with an ideal STRETCH signal, one can get an intermediate-frequency (IF) signal which includes the amplitude and phase characteristics of the linear system. The analysis results given in the paper indicate that the amplitude-frequency characteristic of the IF signal is modulated by that of the linear system, and the phase-frequency characteristic of the IF signal is modulated by that of the linear system.

When an ideal STRETCH signal passes through a linear system and then the output signal is mixed with an ideal STRETCH signal, one can get an intermediate-frequency (IF) signal which includes the amplitude and phase characteristics of the linear system. The analysis results given in the paper indicate that the amplitude-frequency characteristic of the IF signal is modulated by that of the linear system, and the phase-frequency characteristic of the IF signal is modulated by that of the linear system.

理想的STRETCH信号经过线性系统之后,再与理想的STREICH信号混频所得的中频信号中,包含了线性系统的幅相特性,本文分析指出,该中频信号的幅频特性被线性系统幅频特性所调制,其相频特性被线性系统相频特性中偏离直线部分所调制。

The feasibility of the application of a short-stretch signal to ISAR imaging is discussed. The quadratic phase of the short-stretch signal and the effect of the quadratic phase on imaging and scatter-center motion compensation [1] are analyzed in detail. A mo- tion compensation scheme for eliminating the effect of the quadratic phase of the short-stretch signal is put forward. The theoretical analysis and computer simulation show that this scheme works.

论文讨论了窄Stretch信号用于ISAR成象的可行性。详细地分析了窄Stretch信号所特有的平方相位项对成象及散射重心运动补偿法的影响,并提出了一种消除平方相位项影响的运动补偿方法。理论分析与计算机模拟都表明了这种方法是有效的。

The imaging method on low-altitude target in strong ground clutter is presented. The identical amount of stretching time-delay with the adjoined echoes is applied in the signal stretching process, and then the ground clutter is filtered through the one-order canceller. Furthermore the target's motion parameters can be accurately estimated by the narrow pulse signals on the constant carrier, so the motion compensation can be achieved. After the theoretical analysis, the validity is proven by simulation results...

该文中提出了在强地杂波背景下对运动目标的成像方法,在对拉伸(stretch)信号的处理时,采用了前后两次回波使用同一拉伸延时量进行处理的方法,然后使用一次相消器滤除杂波,利用测距用的常载频信号完成精确运动参数的估计并完成运动补偿,经过理论分析和仿真实验验证了该方法的有效性。
