The present invention relates to a radar reflection signal simulator, and more particularly, to a device (10) for generating one or more radial reflective signals indicative of one or more remote objects useful in ground, marine and aircraft radar systems (16) )to be.;The device generates one or more reflected signal scenarios that can interact with the actual or preprogrammed motion of the aircraft on which the controller 16 is mounted, if desired. The output of the internal test signal 21 of the radar itself is used to modify the radio frequency portion of the device that applies the remote object reflection signal scenario to the aircraft radar device 16 so that the operation of the reflected signal generating device can be accurately and reproducibly done.;In order to further improve the precision of the reflected signal, a digital first-in-first-out (FIFO 32) delay means is used to precisely allow delayed reuse of the radar's own transmitted signal.
