The creator and owner of cadRCS Gert Albert Lindqvist (GAL) has been studying Theoretical Physics at the DTU (Danmarks Tekniske Universitet = Technical University of Denmark) and worked then as a scientific employee at the Danish Defence Research Establishment (DDRE) from 1982 to 1999. In the period from 1984 to 1999 GAL developed codes for an experimental radar at DDRE and was involved in several radar measurements.
The experience with these radar measurements gave GAL the opportunity for developing a new theory for calculating RCS. This theory is validated by the different measurements GAL has been participating in. After GAL stopped working for DDRE in 1999, the theory was implemented in the code cadRCS.
