比较了方位向预滤波降采样方法与子孔径处理方法各自的优缺点。
The advantage and disadvantage of the method of azimuth pre-filtering and undersampling and the method of subaperture processing are compared.
在此基础上，本文着重从空间降采样解码与时间降采样解码两方面对降采样解码处理技术进行研究。
On this basis, this paper focuses on two approaches of down-conversion decoding: spatial down-conversion decoding and temporal down-conversion decoding.
用传统MR图像重建方法对降采样数据进行重建往往会产生严重的伪影或导致重建图像的信噪比下降。
Reconstructing MR images from under-sampled measurement data using traditional reconstruction methods usually results in image artifacts and low signal to noise ratio.
综合孔径雷达(SAR)实时成像处理器，在满足分辨率的情况下，通过预滤波和降采样的方式降低数据率来满足系统处理带宽的要求。
Under the condition of meeting resolution, the SAR real-time imager can satisfy the demands of the processing band by pre-filter and down-sample.
