WebThe three-step process is illustrated in Fig. 3. Steps 1 and 3 require N and M multiplications, respectively, and step 2 is a convolution which may be computed by the high-speed technique disclosed by Stockham [3], based on the use of the FFT. Step 2 is the major part of the computational effort and requires a time roughly pro- Web1 is a chirp, and 2 is the phase variation due to the stepped variety of the carrier frequency of the signal. Thus, the signal processing is implemented by the fol-lowing two steps: (1) the pulse compression of the chirp at each PRT gives the coarse range profiles; (2) the inverse dis-crete Fourier transform (IDFT) of the coarse range profile philips hdr5710
