Information theoretic waveform design with applications to adaptive‐on‐transmit radar

open access: yesIET Radar, Sonar & Navigation
The marginal Fisher information (MFI) metric is used to design waveforms for the sake of informationally optimal adaptive‐on‐transmit radar operation. A framework for MFI waveform design is developed and the Polyphase‐Coded FM (PCFM) waveform model is ...

Rough surface scattering based on facet model [PDF]

open access: yes
A model for the radar return from bare ground was developed to calculate the radar cross section of bare ground and the effect of the frequency averaging on the reduction of the variance of the return.
