The Applying of Compressed Sensing in M-Sequence UWB Radar

A maximum length binary sequence, in short an M-sequence, is a special kind of pseudo-random binary sequence(PRBS). It can be well used in Ground Penetrating Radar(GPR) because of advanced characteristics. Compressed Sensing(CS) provides a way to sample the signal below the Nyquist rate, but it relies on two principles: sparsity, which pertains to the signals of interest, and incoherence, which pertains to the sensing modality. M-sequence matrix has been proved satisfying RIP property. In this paper we will introduce a M-sequence GPR system and the CS theory will be used to reconstruct the signal when the original signal is extracted. The experiment results will also be given.
