A multipurpose radar target

Consideration of methods of simulating a moving target by making a mechanically stationary target appear [to an MTI (Moving Target Indicator)-equipped radar] to be moving resulted in the use of crystals as switching elements in a low-voltage low-energy battery-powered device. Extending the use of these switching elements results in a target that is visible to any polarization. By applying these concepts to composite waveguide structures, a dual-band simulated target head was developed and field tested.
