Abstract:

A system for simulating, in the elevation dimension, an environment of targets, ground clutter and chaff to a frequency scan inertialess three-dimensional radar system transmitting frequency differentiated pencil beams to provide an elevation scan. To generate targets, the radar elevation simulation system determines the pencil beams in which a simulated target would appear and generates simulated target echo signals, frequency and time differentiated to correspond to the frequency and transmission time for the selected beams. For passive interference generation, the elevation simulation system gates on simulated ground clutter at short range and low elevation angles and simulated chaff at longer range and higher elevation angles and generates corresponding frequency and time differentiated simulated echo signals. The simulated target and simulated passive interference echo signals are mixed and then fed to the frequency scan radar system for conventional presentation on the radar displays. Author
