What are the main methods for detecting drones?

With the rapid development of drone technology, drones have begun to develop towards miniaturization, low cavitation, simplification, low technology, and low cost. With the advantages of standing tall, seeing far, flying fast, moving unobstructed, strong adaptability, and convenient modification, the use of drones has become increasingly common. However, the widespread application of drones has also raised a series of security and privacy issues. In order to maintain public safety and protect the safety of sensitive places, unmanned aerial vehicle (UAV) countermeasures have been widely used. UAV countermeasures mainly include detection and interference. Today, we will talk about the main methods of detecting UAVs.

The common UAV detection equipment in the market today includes radar system, Radio spectrum detection and optical monitoring equipment. These devices can detect drones by monitoring their signals, thermal energy, or visual features. Let's briefly introduce these types of devices below.

1、 Radio spectrum detection

Radio spectrum detection is one of the common means to detect UAVs. By monitoring and analyzing radio signals in the spectrum, the presence and location of drones can be determined. Drones typically emit radio communication signals, navigation signals, or other characteristic signals that can be captured and recognized by detection equipment. Radio spectrum detection technology can be used to monitor UAV activities in civilian and military fields, and provide important information for countermeasures.

2、 Radar system

Radar system is a common technical means for detecting drones. By utilizing radar technology, it is possible to transmit radio waves and receive reflected signals, thereby achieving remote detection and tracking of unmanned aerial vehicles. By analyzing the data returned by the radar, information such as the position, speed, and flight trajectory of the drone can be obtained. Radar systems are widely used in the field of unmanned aerial vehicle countermeasures, providing important support for defending against unmanned aerial vehicle violations and air surveillance.

3、 Optical surveillance

The unmanned aerial vehicle optoelectronic monitoring equipment consists of a tracking turntable and an optoelectronic cabin, which is equipped with a non cooled infrared focal plane detector, a high-definition visible light camera, and an image processing board. The photoelectric tracking system completes the initial alignment of the target based on the target position information provided by the search system, and then searches for the target near the initial alignment area. During the search process, suspicious targets can be confirmed through automatic identification or manual designation, and then enters the automatic target tracking mode, enabling the photoelectric sensor's line of sight and the radio frequency interference antenna installed on the tracking turntable to align with the target in real-time. Optical sensors can monitor the activity of drones in real-time, which is particularly effective for achieving close range detection and outdoor environment detection.

The main means of detecting UAVs include Radio spectrum detection, radar system, photoelectric monitoring equipment, etc. The combination of these means in practical applications can provide a comprehensive and accurate UAV detection capability. However, with the continuous development of drone technology, there is still an urgent need for continuous research and improvement of detection methods to address the constantly changing threat challenges of drones.
