A Statistical Glint/Radar Cross Section Target Model

We review the details of the glint (angular scintillation) problem in electromagnetic scattering. These results are employed to develop a statistical glint and radar cross section (RCS) target model featuring the correct glint probability density function, the correct time correlations of RCS and glint, and the correct cross correlation between RCS and glint. This model is suitable for simulation applications, and an implementation scheme for a glint/RCS signal generator is included.     

Diversity methods in phase monopulse tracking-a new approach

A novel approach relating target glint (difference between the phase-front gradient of the scattered field and the true target direction vector) to the analytic properties of the overall field is used to suggest a method by which the error in conventional (single frequency) phase monopulse trackers can be reduced. The approximate relationship between glint and amplitude is briefly developed, and an improved glint reduction scheme appropriate for single frequency data is described. The effectiveness in reducing direction angle error is demonstrated with simulated data. It is shown how techniques devised for multiple frequency data sets can be applied to multiple aspect data sets.<>     

Requirements for optimal glint reduction by diversity methods

Target “glint” (the difference between the phase-front gradient of the scattered field and the true target direction vector) is related to the analytic properties of the scattered field. The resulting model is used to reinterpret diversity methods for glint reduction and to more accurately specify system requirements. A relationship for estimating the best possible improvement in target bearing estimation is also developed
