Gridless Quadrature Compressive Sampling with Interpolated Array Technique
Abstract—Quadrature compressive sampling (QuadCS) is a sub-Nyquist sampling scheme for acquiring in-phase and quadrature (I/Q) components in radar. In this scheme, the received intermediate frequency (IF) signals are expressed as a linear combination of time-delayed and scaled replicas of the transmitted waveforms. For sparse IF signals on discrete grids of time-delay space, the QuadCS can effi...
متن کاملQuadrature compressive sampling SAR imaging
This paper presents a quadrature compressive sampling (QuadCS) and associated fast imaging scheme for synthetic aperture radar (SAR). Different from other analog-to-information conversions (AIC), QuadCS AICs using independent spreading signals sample the SAR echoes due to different transmitted pulses. Then the resulting sensing matrix has lower correlation between any two columns than that by a...
متن کاملQuadrature sampling phase detection
The demodulation of phase encoded high frequency carrier signals is a problem encountered in many applications and areas of research. Numerous electronic methods for demodulation of the carrier, including digital counting techniques and quadrature mixing demodulation have become standard.l Alternatively, the waveforms can be digitized and the phase extracted computationally.Q As the carrier fre...
متن کاملEigenstructure beamspace root estimator bank with interpolated array
A beamspace root modification of PseudoRandom Joint Estimation Strategy (PR-JES) [1] is developed. The essence of PR-JES is to generate the eigenstructure-based estimator bank for given sample covariance or data matrix. Combining the results of “parallel” underlying estimators, PR-JES removes the outliers and improves the threshold performance. In the case of non-uniform array, the interpolated...
متن کاملReducing ADC Sampling Rate with Compressive Sensing
Many communication systems involve high bandwidth, while sparse, radio frequency (RF) signals. Working with high frequency signals requires appropriate system-level components such as high-speed analog-to-digital converters (ADC). In particular, an analog signal should be sampled at rates that meet the Nyquist requirements to avoid aliasing. However, implementing high-speed ADC devices can be a...
