Abstract
According to one embodiment, a radar return signal processing apparatus includes a detector, an estimation unit and an extraction unit. The detector detects an average Doppler frequency, a spectrum width, and a received power of each of echoes, from a radar return signal obtained repeatedly at regular intervals. The estimation unit estimates an optimum mixed density function by learning modeling a shaped of the frequency spectrum by calculating repeatedly a sum of density functions of each of the echoes. The extraction unit extracts information on any one of the echoes included in the radar return signal, from a parameter of the estimated mixed density function.
