With the present configuration of the RFSS it is possible to simulate realistic clutter for a semi-active missile seeker system. The proposed model will be based on homogeneous terrain so that it will be possible to precompte certain parameters that describe the Doppler spectrum of the clutter signal as a function of the engagement geometry. The basic methodology is discussed, although much research still must be done to relate the clutter parameters to the specific engagement geometry. The goal of the simulation will be to create a signal that has the proper Doppler spectrum in terms of shape and location. Energy will be generated at the proper spectral band that is a function of the engagement geometry, and considerable care will be taken to avoid generating energy in those spectral bands where there is no clutter. Less emphasis will be placed on generating the correct statistics of the clutter since this aspect of the problem is still controversial and it is more costly to simulate non-Rayleigh signals. The nonhomogeneous nature of clutter, while it represents more realism, is an unwarranted complexity at this stage of hardware-in-the-loop simulation technology.
