SUMMeR: Sub-Nyquist MIMO Radar
Multiple input multiple output (MIMO) radar exhibits several advantages with respect to traditional radar array systems in terms of flexibility and performance. However, MIMO radar poses new challenges for both hardware design and digital processing. In particular, achieving high azimuth resolution requires a large number of transmit and receive antennas. In addition, the digital processing is ...
متن کاملSub-Nyquist Radar: Principles and Prototypes
In the past few years, new approaches to radar signal processing have been introduced which allow the radar to perform signal detection and parameter estimation from much fewer measurements than that required by Nyquist sampling. These systems referred to as sub-Nyquist radars model the received signal as having finite rate of innovation and employ the Xampling framework to obtain low-rate samp...
متن کاملA Sub-Nyquist Radar Prototype: Hardware and Software
We introduce a full hardware implementation and demo of a sub-Nyquist radar receiver. Our system demonstrates pulse-Doppler radar transmission and reception at sub-Nyquist rates. Specifically, we sample the received radar signal at 1/20 the Nyquist rate, while still perfectly detecting the targets in the delayDoppler plane. In addition our system filters clutter interference from the sub-Nyquis...
متن کاملA Sub-Nyquist Radar Prototype: Hardware and Algorithms
Traditional radar sensing typically involves matched filtering between the received signal and the shape of the transmitted pulse. Under the confinement of classic sampling theorem this requires that the received signals must first be sampled at twice the baseband bandwidth, in order to avoid aliasing. The growing demands for target distinction capability and spatial resolution imply significan...
متن کاملSub-nyquist Multicoset and Mimo Sampling: Perfect Reconstruction, Performance Analysis, and Necessary Density Conditions By
We study two sub-Nyquist sampling schemes for multiband signals known as multicoset sampling and multiple-input, multiple-output (MIMO) sampling. A multiband signal is one whose Fourier transform is supported on a set F ⊆ R consisting of a finite union of intervals. Unlike uniform sampling, multicoset sampling allows perfect reconstruction of a multiband input at sampling rates arbitrarily clos...
