On blind searches for noise dominated signals: a loosely coherent approach [PDF]
, 2010 We introduce a ‘loosely coherent’ method for detection of continuous gravitational waves that bridges the gap between semi-coherent and purely coherent methods.

Orthogonal waveform separation based on echo compression for airborne MIMO-SAR systems
The Journal of Engineering, 2019 Attention has been devoted to multi-input multi-output (MIMO) synthetic aperture radar (SAR) systems in recent years. The applications of MIMO-SAR systems which involve high-resolution wide-swath remote sensing, three-dimensional imaging, and multi ...

Generalised RAO test for polarimetric target detection
The Journal of Engineering, 2019 Here, a generalised Rao test method is presented for polarimetric multichannel adaptive signal detection. By introducing several tunable parameters into the Rao test detection statistics, the proposed polarimetric detector is quite general with the ...

Gravitational waves from eccentric compact binaries: Reduction in signal-to-noise ratio due to nonoptimal signal processing [PDF]
, 1999 Inspiraling compact binaries have been identified as one of the most promising sources of gravitational waves for interferometric detectors. Most of these binaries are expected to have circularized by the time their gravitational waves enter the ...

Radar matched filtering using the fractional fourier transform [PDF]
, 2010 -A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be ...
