Although the beginning of research on automotive radar sensors goes back to the 1960s,
automotive radar has remained one of the main drivers of innovation in millimeter wave …

Modern cameras typically use an array of millions of detector pixels to capture images. By
contrast, single-pixel cameras use a sequence of mask patterns to filter the scene along with …

压缩感知是建立在矩阵分析, 统计概率论, 拓扑几何, 优化与运筹学, 泛函分析等基础上的一种
全新的信息获取与处理的理论框架. 它基于信号的可压缩性, 通过低维空间, 低分辨率, 欠Nyquist …

Synthetic aperture radar (SAR) image formation can be treated as a class of ill-posed linear
inverse problems, and the resolution is limited by the data bandwidth for traditional imaging …

摘要经典的香农采样定理认为, 为了不失真地恢复模拟信号, 采样频率应该不小于奈奎斯特频率(
即模拟信号频谱中的最高频率) 的两倍. 但是其中除了利用到信号是有限带宽的假设外 …

摘要在传统采样过程中, 为了避免信号失真, 采样频率不得低于信号最高频率的2 倍.
然而对于数字图像, 视频的获取, 依照香农(Shannon) 定理会导致海量采样数据 …

This paper investigates the problem of estimating the frequency components of a mixture of
s complex sinusoids from a random subset of n regularly spaced samples. Unlike previous …

Compressive sensing (CS) is a novel sampling paradigm that samples signals in a much
more efficient way than the established Nyquist sampling theorem. CS has recently gained a …

The class of L1-regularized optimization problems has received much attention recently
because of the introduction of “compressed sensing,” which allows images and signals to be …
