Efficient knowledge-aided target relocation algorithm for airborne radar

open access: yesThe Journal of Engineering, 2019
This letter addresses the problem of target relocation in wide-area ground moving target indication system. The antenna pattern information is exploited as prior knowledge to enhance the performance of airborne radar. Firstly, the ideal target relocation

Work measurement as a generalized quantum measurement [PDF]

open access: yes, 2014
We present a new method to measure the work $w$ performed on a driven quantum system and to sample its probability distribution $P(w)$. The method is based on a simple fact that remained unnoticed until now: Work on a quantum system can be measured by ...

Airborne Millimeter-Wave InSAR Terrain Mapping Experiments Based on Automatic Extraction and Interferometric Calibration of Tie-Points

open access: yesRemote Sensing, 2023
Limited by meteorological conditions, airspace, complex terrain and other factors, airborne millimeter-wave InSAR will inevitably face the situation of no control point layout when acquiring terrain data in the difficult mapping areas in Southwest China,

Experimental Demonstration of Optimal Unambiguous State Discrimination [PDF]

open access: yes, 2000
We present the first full demonstration of unambiguous state discrimination between non-orthogonal quantum states. Using a novel free space interferometer we have realised the optimum quantum measurement scheme for two non-orthogonal states of light ...

Information-Disturbance Tradeoff in Quantum State Discrimination [PDF]

open access: yes, 2006
When discriminating between two pure quantum states, there exists a quantitative tradeoff between the information retrieved by the measurement and the disturbance caused on the unknown state.
