A stationary area weapon effects simulator is mounted to the ceiling of a room in a building being assaulted by soldiers equipped with optical detectors and small arms weapons having small arms transmitters (SATs). Area effects weapon codes simulating the detonation of a grenade, bomb, artillery shell or chemical/biological weapon are encoded onto infrared signals emitted by a plurality of LEDs in the weapon effects simulator and these codes are logged in player units (DPCUs) carried by the soldiers. The simulated area weapon effects may be confined to particular angular zones and this zone information may also be encoded onto the infrared emissions. An alternate embodiment utilizes a stationary locator in a room which only emits infrared signals with location information encoded in the same which are logged by the player unit. Area weapon effects and location information may be downloaded from the player units, along with conventional casualty, near miss and time of occurrence data for assessment of tactics and weapons usage accuracy during after action review (AAR) by an instructor. A red rotating beacon may be added to the area weapon effects simulator to indicate the simulated detonation and/or to indicate that a structure such as a bridge has been blown up and can no longer be used. The area weapon effects simulator can be activated by sending an RF command received through a pager, or by manual devices such as an electro-mechanical switch connected to a trip wire.

System and method for training in military operations in urban terrain

Systems and methods for determining the range from a vehicle to a plurality of reference points. In one system a mobile transceiver is located on the vehicle for transmitting a ranging interrogation signal pulse modulated on an RF carrier having a given frequency in response to a timing pulse and for receiving ranging response signal pulses modulated on RF carriers having the given frequency. A plurality of reference transponders are individually located at each of the plurality of reference points for receiving the timing pulse and the ranging interrogation signal pulse on a carrier having the given frequency and for responding thereto by transmitting a ranging response signal pulse on a carrier having the given frequency during an interval that is discrete from the intervals during which ranging response signal pulses are transmitted from the other reference transponders. Within a given time slot in relation to the timing pulse, a single ranging interrogation signal pulse is followed by a sequence of discrete ranging response signal pulses. A data processor determines and processes the phase of the received ranging response signal pulses in relation to the transmitted ranging interrogation signal pulse to determine the range from the vehicle to individual reference points, and processes the range determinations to determine the position of the vehicle by multilateration. The mobile transceiver, transponders, and transmitter each include an RF transmitter having a modulator circuit for modulating an RF carrier signal to have a predetermined shape envelope determined by the shape of a modulating signal.
