Overview of Drone Defense and Countermeasure Applications

Abstract: With the popularization of drones, both military and civilian fields are facing increasingly serious drone threats, and anti-drone technology has become a key technology of concern to all countries. The technical threshold and difficulty of drone acquisition are constantly decreasing, and the frequency of use of drones converted from civilian to military use in terrorist attacks, armed conflicts and other fields is increasing. The targets of the attacks are mainly military, economic, political, livelihood and other facilities and key political figures. In order to effectively resist the security threats posed by drones, especially small civilian drones, domestic and foreign manufacturers have developed and produced a large number of drone countermeasure equipment systems. In general, these equipment systems basically adopt the operating logic of detection, monitoring, positioning, tracking and countermeasure, mainly including radar, optoelectronics, radio reconnaissance and interference, navigation deception and other equipment. These anti-drone equipment are currently being used more and more widely.

00001. Target Analysis

Due to the small size of drones and the light color of some drones, the color difference between them and the sky is small. Under normal circumstances, drones 200 to 300 meters away are basically impossible to detect with the human eye. Illegal drones may pose a potential and real threat to maintaining public safety and normal production and living order, which can be divided into three aspects:

· Peeping in the sky

The flying height of drones exceeds most obstacles, and they can easily take photos and videos of key parts of high-walled courtyards. Drones have relatively complete camera stabilization technology, flight recording systems, and real-time image return systems. They have the functions of fixed-point cruise shooting, follow-up shooting, and surround shooting, and can be used for espionage activities without modification.

Due to the tight ground security and prevention measures at major events or around important facilities, criminals may use drones to carry explosives, biological agents, radioactive materials or illegal propaganda to throw into the venue. Using GPS navigation technology, even in the dark night, drones can fly over the walls and fences of the target area and accurately deliver harmful items to the designated location without alerting the security personnel and alarm equipment. The drone bomb targeting the Venezuelan president has given society a great warning.

Technological Advancements, Enhanced Image Quality

The upgraded AI PTZ camera is equipped with the latest STARVIS CMOS sensor, delivering ultra-high-definition image quality that captures clear and detailed footage even in challenging lighting conditions. With its high optical zoom and digital zoom capabilities, users can flexibly adjust the monitoring range to ensure seamless surveillance coverage.
