High-resolution imaging radar for detecting foreign objects of runways

Abstract

The invention provides a high-resolution imaging radar for detecting foreign objects of runways. The high-resolution imaging radar comprises a radar rotating unit and a fixing unit. A millimeter wave transceiving module, a transmitting antenna and a receiving antenna are disposed on the radar rotating unit. The millimeter wave transceiving module transmits a millimeter wave signal through the transmitting antenna. The receiving antenna receives an echo single of a target. The echo signal enters the millimeter wave transceiving module to obtain a beat signal. The beat signal is processed by a signal processing module to obtain the distance between the target and the radar. High-resolution imaging detection of a to-be-detected area is achieved by using the millimeter wave frequency modulated continuous wave radar, the radar is high in resolution, the details of the target can be observed clearly, and target detection and identification are facilitated.

Description

technical field [0001] The invention relates to an imaging radar for detecting foreign objects on airport runways, more specifically, to a high-resolution imaging radar for detecting foreign objects on airport runways using a frequency modulation wave system, which can be used for detecting, alarming and locating foreign objects on various airport runways. Background technique [0002] The airport runway is an open-air dedicated road surface for aircraft take-off, landing, and rolling. It not only bears the take-off and landing load of the aircraft, but also is affected by factors such as damage to the road surface and foreign objects. Take-off and landing will cause major safety incidents and pose a serious threat to the engine, fuselage, tires, etc. of the aircraft. In light cases, it will cause serious economic losses and affect the normality of flights. In severe cases, it may cause flight-level accidents and air crashes. The existence of foreign objects on airport runwa...

Problems solved by technology

[0002] The airport runway is an open-air dedicated road surface for aircraft take-off, landing, and rolling. It not only bears the take-off and landing load of the aircraft, but also is affected by factors such as damage to the road surface and foreign objects. Take-off and landing will cause major safety incidents and pose a serious threat to the engine, fuselage, tires, etc. of the aircraft. In the light cases, it will cause serious economic losses and affect the normality of flights. In severe cases, it may cause flight-level accidents and air crashes, etc.

The existence of foreign objects on airport runways not only causes huge direct losses to airports in various countries, but also causes indirect losses such as flight delays, interrupted takeoffs, and closure of runways due to the occurrence of incidents.

In order to remove foreign objects on the airport runway, the traditional method is to rely on manual inspection. However, due to the frequent take-off and landing of airport aircraft, the manual inspection method is time-consuming and laborious. Each inspection of foreign objects on the runway will affect the normal take-off and landing of multiple flights. More importantly, Relying on manual detection is easy to miss foreign objects or detect foreign objects dropped from vehicles, which has serious defects in the detection of foreign objects on the road surface

[0003] At present, using manual detection methods to detect foreign objects on airport runways can no longer meet the needs of major airports for the safety protection of airport runways
