Laser imaging radar target echo signal simulator

Abstract

The invention relates to a laser imaging radar target echo signal simulator in a laser imaging radar guidance semi-physical simulation system, and belongs to the technical field of electro-optical information systems.The target echo signal simulator comprises a reflecting memory card, a target scene generation computer, a synchronizing signal receiver, a signal distributor, an echo signal generator, a light source driving device and a light source array.The target scene generation computer receives target track data transmitted by a simulation computer in real time, generates delay data and pulse width data according to a data generation method and transmits the data to the echo signal generator.Under triggering of a triggering signal, the echo signal generator conducts delaying and widening on the current delay data and the pulse width data, and the light source array is driven by the light source driving device to transmit multiple paths of optical echo signals.The simulator is high in integration level and stability and has the advantage of providing multiple paths of the real-time optical echo signals which are physical, wide in delay range, high in time accuracy and adjustable in pulse width for a tested laser imaging radar sensor.
