Waveform Design for Improved Detection of Extended Targets in Sea Clutter [PDF]

open access: yesSensors, 2019
Adaptive waveform design for cognitive radar in the case of extended target detection under compound-Gaussian (CG) sea clutter is addressed. Based on the CG characteristics of sea clutter, the texture component is employed to characterize the clutter ...
