| 摘 要： | 在机载SAR的实时成像处理器中,回波信号方位向带宽以及方位向采样率不能很好的满足成像处理的要求,本文选择ADSP-TS201处理器芯片对回波信号在成像之前对其进行方位向预处理。在软件实现过程中充分利用此芯片的功能特点,使得预处理在精确度和效率上都很好的满足了成像处理的要求。

| Abstract: | In an airborne SAR Real-Time Imaging System, the echo signal cannot fully satisfy the demands of imaging as its wide bandwidth and high Pulse Repetition Frequency (PRF) in azimuth. This paper presents the design scheme of preprocessing the echo signal before imaging, which selects ADSP-TS201 as the processor. Trying to take full advantage of the DSP chip during the software design flow, the results show the good feasibility of the proposed design scheme in precision and efficiency. |
