e error meaning in English

错误，差错（故障显示）
失误
误差

E error returned because result length is too short to display
E =因为结果长度太短无法显示而返回错误。
Thirdly , a modified extended chirp scaling ( ecs ) algorithm is presented , which solves the problem of producding fine focused images in the class of chirp scaling ( cs ) algorithm . lt can be used for uwb - sar imaging effectively . the phas e error produced by cs operation are analyzed . a windowed process in two dimension frequency domain before cs operation are proposed . it can improve the quality of image and widen the effectively swath and increase the peak to sidelobe ratio ( pslr )
然后针对chirpscaling ( cs )类算法不能对参考点精确聚焦的问题，提出了一种改进的扩展cs ( ecs )算法，实现了对uwb - sar的高效成像；分析了cs操作产生的相位误差，提出在cs操作之前在二维频率域对信号加窗，除有效提高信号的峰值旁瓣比( pslr )外，还可以提高图像质量，增加有效测绘带宽度。
