Numerical and experimental verifications of digital correlator model for random noise radar

Design theory and efficient digital correlator model of a random FM noise radar was presented. The correlator model was developed with System generator blocksets in Simulink environment to include the discrete time base and quantization effect if it can be implemented by using the FPGAs available in the markets. Numerical simulation was conducted with the virtual noise signal and moving target signal generators, and the obtained results show good agreements with the expected values. For an experimental examination, a mm-wave random FM noise radar was implemented based on the obtained design parameters, and a field test was made for detecting a high-speed moving target. With the logging data, an off-line correlation and Doppler processing was made, and the obtained information was very close to the estimated one again. All the results fully validate the design theory and the developed digital correlator model.
