This report describes a real-time simulation procedure for generating replicas of the ground clutter signal as received on the three monopulse channels of an airborne radar. The procedure is based on first computing the power spectra of the clutter on the three monopulse channels according to the engagement geometry, then randomizing these power spectra, and finally executing an FFT in real time to create the quadrature video components of the clutter sequences. The procedure permits any spectra shape to be simulated, so that it is inherently very accurate. However, the computation is time-consuming so that its application in real time is limited. With one AP120B array processor interfaced to a Data craft6 computer, only a signle range gate of clutter can be simulated in real time. Listings of a Fortran program are included. The program has been tailored to a specific missile system under test at the RFSS.
