A reusable general aviation simulator

Abstract

The invention provides a multiplexing general aviation simulator, the clock module is used to provide 100MHz-6GHz and 3-20GHz local oscillator signals; the baseband signal generator is used to generate and output baseband signals; The ‑6GHz local oscillator signal modulates the baseband signal to form the transmit signal of the simulated simulator; the 20G up-conversion module modulates the baseband signal according to the 3‑20GHz local oscillator signal to generate the required simulated simulator signal Signal transmission; the dual-channel down-conversion module demodulates the externally input RF signal according to the 3-20GHz local oscillator signal to form an intermediate frequency signal; the 20G down-converter module uses the 3-20GHz local oscillator signal to demodulate the externally input RF signal Perform demodulation to generate an intermediate frequency signal; a dual-channel digitizer module is used to sample the intermediate frequency signal AD and perform signal processing to complete signal spectrum analysis and / or demodulation analysis. The invention can simulate various aircrafts, greatly reducing the volume and cost of the traditional multi-simulator system.

Description

technical field [0001] The invention belongs to the technical field of general aviation testing, in particular to a reusable general aviation simulator. Background technique [0002] The existing simulator equipment mainly adopts the traditional single independent design idea. Technically, it only needs to collect and transmit signals through a simple embedded controller and peripheral AD / DA components. This method is characterized by a relatively simple design. For the demand of a single simulator, it is feasible to a certain extent, but it has the disadvantages of large size and no scalability. When multiple types of simulators are required to coordinate their work, it is necessary to pile up and use multiple simulators of different types. Each simulator is an independent embedded control system. Such an overall design has a large volume and low resource utilization. , the disadvantage of inconvenient use. Contents of the invention [0003] In view of this, in order to...
