Anatomy of a Digital Coherent Receiver
Digital coherent receivers have gained significant attention in the last decade. The reason for this is that coherent detection, along with digital signal processing (DSP) allows for substantial increase of the channel capacity by employing advanced detection techniques. In this paper, we first review coherent detection technique employed in the receiver as well as the required receiver structu...
متن کاملNext Generation Phase Coherent Instrumentation Receiver
The next generation of antennas will benefit from advanced instrumentation receivers capable of providing simultaneous analog and digital IF inputs, better TR pulse synchronization and high resolution pulse profiling. One such receiver uses a synergistic combination of a tightly coupled FPGA based beam controller, high performance analog digitizers, multiple FPGA based digital signal processors...
متن کاملCoherent Receiver Arrays for Astronomy and Remote Sensing
The Keck Institute for Space Studies (KISS) was established at Caltech in January 2008 with a $24 million grant over 8 years from the W. M. Keck Foundation. The Institute is a " think and do tank, " whose primary purpose is to bring together a broad spectrum of scientists and engineers for sustained technical interaction aimed at developing new space mission concepts and technology. The best ex...
متن کاملContribution of Auxiliary Coherent Radar Receiver to Target’s Velocity Estimation
Recent progress in bistatic radar techniques can be used to improve performances of classical monostatic radar. A prominent limitation of coherent radar is its inability to measure the complete velocity vector (magnitude and direction) of a detected target. A single coherent detection can provide range-rate only. At least two detections, separated in time, are needed to estimate the target’s ve...
متن کاملCoherent Receiver Based on a Broadband Optical Phase-Lock Loop
We propose and demonstrate a 1.45GHz bandwidth optical phase-lock loop receiver for linear optical phase demodulation. Using the receiver in a link application, a spurious free dynamic range of 125 dBHz is measured at 300MHz. ©2007 Optical Society of America OCIS codes: (250.3140) Integrated optoelectronic circuits, (060.1660) , Coherent communications (060.5060), Phase modulation, (060.2360) F...
