Abstract

The invention discloses a foresight view reinforcement device applied to low-altitude flight safety. The foresight view reinforcement device applied to low-altitude flight safety comprises a transmitting antenna, a receiving array control switch matrix containing a transmitting power amplifier connected with the transmitting antenna, and an internal standard module, a transmitter connected with the transmitting power amplifier and the internal standard module respectively, an array receiving antenna connected with the internal standard module, a receiver containing a radiofrequency receiver connected with the internal standard module, and an intermediate-frequency orthogonal demodulation receiver which are sequentially connected, a digital signal processing and control system connected with the intermediate-frequency orthogonal demodulation receiver, and a frequency synthesizer connected with the internal standard module, the transmitter, the radiofrequency receiver, the intermediate-frequency orthogonal demodulation receiver and the digital signal processing and control system respectively. The foresight view reinforcement device applied to low-altitude flight safety disclosed by the invention is capable of realizing imaging for targets dead ahead, and in front and below a flight route, meeting the needs of general aircraft avoidance, low-altitude obstacle avoidance, aircraft blind landing and the like during low-altitude airspace flight, and effectively solving the safety problem of civil low-altitude flight aircrafts during low-altitude flight.

Description

technical field [0001] The invention relates to a forward-looking visual enhancement device, in particular to a forward-looking visual enhancement device applied to low-altitude flight safety, and relates to the technical field of radar. Background technique [0002] Traditional synthetic aperture radars can only image and observe targets on the left and right sides of the flight direction of the aircraft, and cannot cover the targets directly in front of and below the flight path, so there are inherent blind spots in the imaging area. With the opening of low-altitude airspace, problems faced by aircraft in low-altitude airspace, such as general aircraft avoidance, low-altitude obstacle avoidance, and aircraft blind landing, require the use of forward-looking vision enhancement technology to detect targets in the airspace directly in front of the aircraft. scene for imaging observations. [0003] The airborne forward-looking visual enhancement system uses a working mode sim...

Problems solved by technology

my country started relatively late in the field of SAR, but after nearly 30 years of development, it has successfully developed a practical airborne and spaceborne synthetic aperture radar system, and has been widely used in related fields. Spaceborne SAR research is mainly concentrated in the fields of front-looking and side-looking SAR and squint-looking SAR, but there is still a blank in the field of airborne forward-looking vision enhancement radar research, which is in the initial simulation stage
