RADAR RECEPTION SIGNAL PROCESSING DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To precisely detect, out of radar reception signals which are a mixture of target signals and unnecessary signals whose frequencies vary to substantially the same extent, only the target signals.

SOLUTION: A method comprises: acquisition of a frequency spectrum by converting radar reception signals into a frequency range (step S11); modeling the acquired frequency spectrum with a sum of the density function of each echo group (mixed density function) (step S12); parameters of the mixed density function are presumed by learning an optimal values thereof (step S13); and calculation of the average Doppler frequency, spectral width and electric power for reception from the presumed parameters and outputting the calculated results as observation findings (step S14).
