Embodiment Construction
[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0032] The current shipborne or land-based communication and reconnaissance systems have limited coverage in three-dimensional space, and target signals may be limited by line-of-sight transmission and cannot be effectively reconnaissance. Therefore, large array antennas are usually used to ensure reconnaissance distance and signal gain; Under the circumstances, the UAV platform is flexible and has a wide coverage area. Within the sensitivity range of the receiver, the signal detection distance can be increased by increasing the flight height of the platform, and the overall size of the receiver antenna array can be greatly reduced. The signal environment near the sea surface and the ground is very complex, including not only the target signal, but also many friendly, neutral and non-combatant signals. At the same time, t...

The invention provides a UAV communication reconnaissance system, including an airborne communication reconnaissance antenna pod, an airborne communication reconnaissance receiver, a ground satellite signal processing device, a ground L-band receiving antenna, a display control module and a UAV measurement and control link module. The airborne communication reconnaissance antenna pod intercepts the target signal, and the signal is sent to the airborne communication reconnaissance receiver for processing, and the processed result is transmitted from the UAV measurement and control link module to the display and control module for display; the ground L-band receiving antenna receives the maritime satellite The telephone communication signal is transmitted to the ground satellite signal processing equipment for processing, and the processing result is transmitted to the display and control module for display through the ground station network. The invention can realize functions such as detection, analysis, demodulation, direction finding and positioning of the conventional communication signals and maritime satellite telephone communication signals within the frequency range of 100MHz-2700MHz by the unmanned aerial vehicle.
Description
technical field [0001] The invention belongs to the field of unmanned aerial vehicle communication reconnaissance, and designs a kind of unmanned aerial vehicle communication reconnaissance system. Background technique [0002] The UAV system includes the UAV platform and the ground station. The ground station generally consists of a ground data terminal and a ground command and control station. The UAV platform performs tasks in the air, and the operator controls the aircraft and the load on the aircraft at the operating seat of the ground station to complete the corresponding tasks. [0003] The communication between the UAV and the ground station is completed through a data link, and the data link is divided into a line-of-sight link and a satellite link. The line-of-sight link is mainly to complete the transmission of remote control telemetry information between the UAV and the ground station within the line-of-sight range, and generally the maximum operating distance i...
