Sparse MIMO Array GPR Based on Compressed Sensing
نویسندگان
چکیده
MIMO array can obtain much more equivalent elements by using a small number of transmitters and receivers. However, according to traditional sampling theorem, a certain number of transmitters and receivers are still needed to obtain a dense equivalent array. Since the interesting targets of ground penetrating radar (GPR) are usually sparse, this paper presents a spare MIMO array GPR imaging scheme. Based on compressed sensing theory, the required transmitters and receivers in the MIMO array can be reduced significantly. Experiment results of a vehicle-mounted GPR system are presented to show the validity of the proposed method. Keywords-compressed sensing, GPR, MIMO array, landmine detection

Accelerating Magnetic Resonance Imaging through Compressed Sensing Theory in the Direction space-k
Magnetic Resonance Imaging (MRI) is a noninvasive imaging method widely used in medical diagnosis. Data in MRI are obtained line-by-line within the K-space, where there are usually a great number of such lines. For this reason, magnetic resonance imaging is slow. MRI can be accelerated through several methods such as parallel imaging and compressed sensing, where a fraction of the K-space lines...
متن کاملMultichannel group sparsity methods for compressive channel estimation in doubly selective multicarrier MIMO systems
We consider channel estimation within pulseshaping multicarrier multiple-input multiple-output (MIMO) systems transmitting over doubly selective MIMO channels. This setup includes MIMO orthogonal frequency-division multiplexing (MIMO-OFDM) systems as a special case. We show that the component channels tend to exhibit an approximate joint group sparsity structure in the delay-Doppler domain. We ...
متن کاملCompressed Sensing Application For Sparse Array Radar
Based on the sparsity of scene (moving target and few scatterers on the same resolution cell), MTD and 3D imaging are investigated by means of compressed sensing (CS) for airship sparse array radar and airborne three-aperture MMW SAR. Based on the sparsity of continuous scene sparse spectrum, sidelooking 3D imaging is investigated by means of CS for airborne cross-track sparse array SAR. Some s...

The novelty of this letter is that it capitalizes on noise waveform to construct measurement operator at the transmitter and presents a new method of how the analogue to digital converter (ADC) sampling rate in the monostatic multiple-input multiple-output (MIMO) noise radar can be reduced — without reduction in waveform bandwidth — through the use of compressive sensing (CS). The proposed meth...
متن کاملDictionary Learning Based Sparse Channel Representation and Estimation for FDD Massive MIMO Systems
Downlink beamforming in FDD Massive MIMO systems is challenging due to the large training and feedback overhead, which is proportional to the number of antennas deployed at the base station, incurred by traditional downlink channel estimation techniques. Leveraging the compressive sensing framework, compressed channel estimation algorithm has been applied to obtain accurate channel estimation w...
