Radar transmit waveform design for lossy propagation channels

This paper proposes that radar transmit codes can be tailored to a specific target scene through the use of Marginal Fisher Information (MFI). Where peak sidelobe level (PSL) and Total Integrated Sidelobe Level (TISL) are metrics frequently used in determining the quality of radar transmit codes, well performing free-space waveforms with low PSL and TISL may not be optimal for lossy propagation channels. When some knowledge is available regarding the propagation characteristics of the scene, MFI can be used to develop transmit codes with significantly increased estimation accuracy over codes designed to be optimal for free-space cases.
