Abstract

The invention discloses a semi-physical simulation landing guide analog system based on a decimeter-wave instrument landing system. The semi-physical simulation landing guide analog system is characterized by comprising a ground equipment simulator for simulating a localizer, a glide-slope localizer and a ranging response signal of the decimeter-wave instrument landing system according to an instruction of the simulator and providing simulated angle information and distance information for airborne equipment, and an airborne equipment simulator for demodulating and decoding the simulated information sent from the ground equipment simulator and providing the simulated information to a flying control system. The semi-physical simulation landing guide analog system has the beneficial effects that the processes of navigation audio signal generation, angle beacon calculation and calibration, control and detection and the like are all digitalized; the ground equipment simulator adopts a digital pulse amplitude modulation mode for generating a simulated high angular resolution signal, and the airborne equipment simulator adopts a digital filtering mode and the like for effectively improving the calculating precision and the ranging precision of an angle localizer; the circuit multiplexing degree is high, the working process is stable and reliable, and the intelligentization, integration and miniaturization are realized.

Description

technical field [0001] The invention relates to a semi-physical simulation landing guidance simulation system for an aircraft, especially an unmanned aerial vehicle, in particular to a semi-physical simulation landing guidance simulation system based on a decimeter wave instrument landing system. Background technique [0002] The autonomous landing of airplanes and UAVs is a highly complex and comprehensive research project, and it is a key and difficult issue in current UAV technology. Autonomous landing of UAVs requires not relying on the remote control of ground personnel, but only relying on the guidance signals (heading, glide, distance, and height signals) of the aircraft's airborne equipment and ground guidance equipment to complete the automatic trajectory design and make correct flight control responses. Landing autonomously. One of the main difficulties in the development of UAV autonomous landing system lies in the verification of the system. Since the UAV carri...
