Abstract:

This Fortran program generates continuous time sequences of ground clutter that would be received on an airborne radar platform for a time-varying engagement geometry. Signals are generated for the three monopulse channels. It is assumed that these signals will be radiated into specific positions on the receive antenna pattern so that each signal will be received by the proper channel and rejected by the others. This program was written for a single range gate of a pulse-Doppler radar, although it is easily extended to multiple range gates but not in real time with a single AP120B. The organization of this program is sketched. At the RFSS it is assumed that the real-time state of the environment will be set up in COMMONC1 and periodic calls will be made to CLUTTER in the Datacraft6. The subroutines that actually generate the clutter sequences FILL, CURVE, PARAB, CONVRT, TIMESQ, GAUSS4, FOURT will be implemented in the AP120B. Their Fortran equivalents are included in this package. A test program TEST is also included to compare results on different computers. The output of this program is a power spectral estimate of the clutter sequences generated under stationary conditions.
