high-resolution-one-dimension
高分辨率要求系统具有大的带宽,瞬时带宽的增加必将提高系统对硬件的要求,本文采用方便灵活的步进频率波形信号。脉间频率步进波形通过子脉冲载频的步进变化来获得大的有效带宽,使成像具有高分辨率,采用加窗和补零方法提高信噪比,但该信号对目标径向速度非常敏感。采用补零方法提高距离取样分辨率,使距离像细化,并用公式说明了补零只能提高距离取样分辨率,并不能改变频率步进信号的距离分辨能力。该信号波形对目标径向速度的敏感,使目标能量分散到邻近的距离单元造成距离分辨率下降,如果不事先进行速度补偿,直接对回波信号进行逆傅立叶变换,将使所成一维距离像发生频谱展宽,并伴有距离像发生平移。本文证明了当目标有径向速度时仍采用对回波信号直接进行逆傅立叶变换的方法将使一维距离像发生频谱展宽并伴有距离像发生频移,从而严重影响了一维距离像的质量。(high-resolution requirements of the system with large bandwidth, the increased instantaneous bandwidth will improve the system of hardware, In this paper, a flexible and convenient step frequency signals. Pulse frequency step-pulse waveform through the carrier frequency step to achieve great changes in the effective bandwidth. make imaging with high resolution, increasing the window and fill methods to improve signal-to-noise ratio is, However, the signal on the target radial velocity is very sensitive. Using zero-distance sampling method to improve resolution, so that distance as refinement, and formulates a zero-distance sampling can improve resolution, does not alter the frequency of the signal from stepping resolution capabilities. The signal waveform on the target radial velocity sens)
