Problems solved by technology

Because the design of traditional radio equipment is based on hardware, the function is single and the scalability is poor. Devices with different functions require different hardware designs. The research and development costs are high, and it is difficult to expand and upgrade.
Numerous discrete navigation and communication devices lead to large volume, weight and power consumption of airborne equipment, and lack of versatility and flexibility. Airborne navigation and communication equipment urgently needs an integrated and integrated solution

Abstract

The invention provides a software radio-based airborne navigation and communication processing module. The software radio-based airborne navigation and communication processing module includes a broadband integration radio frequency transceiver part and a data processing part which jointly complete the receiving and sending of navigation communication data; the radio frequency transceiver comprises a band shaping filter, a high-dynamic range ADC, a decimation filter, an FIR filter, an interpolation filter and a high-dynamic range DAC which are connected with one another sequentially, and complete frequency mixing, filtering and AD conversion; and the data processing part can realize multi-channel signal digital filtering, data modulation and demodulation and data packaging and analysis and complete a navigation communication data processing function. With the software radio-based airborne navigation and communication processing module of the invention adopted, the universality and flexibility of airborne equipment can be improved, the development and maintenance cycle of the airborne navigation and communications equipment can be shortened, and the reliability and scalability of the equipment can be improved.

Description

technical field [0001] The invention belongs to the field of aircraft navigation communication design, and relates to an airborne navigation communication processing module based on software radio. Background technique [0002] The new aircraft navigation communication system consists of various airborne radio equipment, including VOR, VHF, ILS and so on. Because the design of traditional radio equipment is based on hardware, it has a single function and poor scalability. Devices with different functions require different hardware designs. The research and development costs are high, and it is difficult to expand and upgrade. Numerous discrete navigation and communication devices lead to large volume, weight and power consumption of airborne equipment, and lack of versatility and flexibility. Airborne navigation and communication equipment urgently needs an integrated and integrated solution. Contents of the invention [0003] In order to solve the technical problems exis...
