MSE lower bounds conditioned by the energy detector [PDF]

, 2007
A wide variety of processing incorporates a binary detection test that restricts the set of observations for parameter estimation. This statistical conditioning must be taken into account to compute the Cramer-Rao bound (CRB) and more generally, lower ...

Method of Range Ambiguity Suppression Combining Sparse Reconstruction and Matched Filter

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Synthetic aperture radar (SAR) images are often affected by range ambiguity due to antenna sidelobe characteristics and pulse operating mechanism. The work of range ambiguity suppression focuses on both SAR system design and signal processing. On the one

Joint Design of Transmit Waveforms for Object Tracking in Coexisting Multimodal Sensing Systems

Sensors, 2019
We examine a multiple object tracking problem by jointly optimizing the transmit waveforms used in a multimodal system. Coexisting sensors in this system were assumed to share the same spectrum.
