The concept was introduced by Claude E. Shannon in his 1948 paper "A Mathematical Theory of Communication". Shannon s entropy represents an absolute limit on the best possible lossless compression of any communication, under certain constraints: treating messages to be encoded as a sequence of independent and identically-distributed random variables, Shannon s source coding theorem shows that, in the limit, the average length of the shortest possible representation to encode the messages in a given alphabet is their entropy divided by the logarithm of the number of symbols in the target alphabet. )

雷达系统建模与仿真：回波波形、中放后波形、I/Q相干检波后波形、脉压后波形、MTI对消后波形、相参积累后波形、取模后波形、cfar后波形(Radar System Modeling and Simulation: echo waveform, the waveform after the release, I/Q coherent detection shaped pulse waveform after, MTI cancellation after wave, after wave coherent integration after modulo waveform, cfar waveform)

FastCSMatrix: The operator form of the contraint matrix for the fast compressed sensing problem. Specifically, it returns y = A*x (mode = 1) or y = A *x (mode = 2), where A is an mxn matrix given by A = [Phi - Phi], and Phi = P*H*Q, where P,Q are random permutation matrices, and H is a fast Hadamard/Fourier operator.
