A stylized compressed sensing radar is proposed in which the time-frequency plane is discretized into an N times N grid. Assuming the number of targets K is small (i.e., K Lt N2), then we can transmit a sufficiently ldquoincoherentrdquo pulse and employ the techniques of compressed sensing...
Compressed sensing (CS) has recently attracted much interest because of its important offerings and versatility. High-resolution radar imaging applications such as through-the-wall radar (TWR) imaging or inverse synthetic aperture radar (ISAR) are two key application areas that can greatly...

Multicarrier waveforms such as orthogonal frequency-division multiplexing (OFDM) found their way into radar applications in the last few years. However, currently, typically only a fraction of the large baseband bandwidth required to obtain high resolution is available in practice due to hardware limit...
In synthetic aperture radar (SAR), an object, such as, for example, the earth's surface, is scanned by a short moving antenna, via which pulse signals, i.e., pulses are emitted at a defined time interval and the echo signals, i.e., the pulse signals reflected by scanned objects, ar...
Bayesian compressive sensing in synthetic aperture radar imaging To achieve high-resolution two dimension images, synthetic aperture radar (SAR) with ultra wide-band faces considerably technical challenges such as long d... J Xu,Y Pi,Z Cao - 《Iet Radar Sonar & Navigation》 被引量: 87发表: ...
Full size image The variation of floodplain flow levels across spatial scales is evaluated by means of the dimensionlessbexponent17to produce a consistent floodplain zoning analysis (see Technical Validation).
