Abstract:

This report extends and updates the computer simulation of Range Relative Doppler Processing RRDP, and Invariant Mapping for MM wave seekers, which was introduced in prior reports. A major difference between standard Synthetic Aperature and RRDP is that the return signal is heterodyned with respect to a synthetic signal corresponding to a fictitious scatterer at the center of the range cell. It follows that the implementation of RRDP depends critically on an accurate simulation of the round trip delay. For this purpose the round trip delay is expressed as a four dimensional third order Taylor expansion. The footprint reflectivity versus azimuth and range is transferred to an absolute x-y map using the Invariant Mapping Technique proposed earlier, which has been greatly improved. This report is concerned with the theory, formulas, Fortran implementation, and performance of the simulation. A separate User Manual is also available in Volume 2. Author.
