The Portable Multi-Band UAV Directional Control Instrument (Low-Altitude Aircraft Radio Link Jamming Equipment), as a professional criminal technical investigation equipment, is mainly applied in criminal investigation on-site protection, illegal crime disposal and forensic identification assistance. It accurately solves the potential risks of low-altitude safety and evidence leakage caused by illegal UAVs, provides key support for case detection and identification work, and serves as a core individual equipment for front-line law enforcement personnel.
In criminal investigation on-site investigation, this equipment is suitable for various core scenarios and builds a solid line of defense for on-site protection. For major crime scenes such as homicides and explosions, it can be quickly deployed to form a temporary low-altitude no-fly zone, counteract illegal UAV photography, prevent the leakage of sensitive information such as the location of on-site physical evidence and investigation details, and ensure the originality of evidence; In cases of combating drug and contraband delivery by UAVs, it can accurately block the link of the criminal UAV and force it to land, providing conditions for arresting operators and fixing criminal tools; In the prevention and control of prisons and classified places, it can prevent UAVs from illegally delivering items and collecting intelligence, strengthen perimeter security, and assist in investigating illegal clues.
In forensic identification, this equipment provides strong support for evidence fixation and case traceability. The countered and forced-landed UAV itself can be used as core physical evidence, and its flight data combined with the equipment's usage records (time and location) can provide key basis for tracing the identity of the UAV operator and analyzing criminal intent; At the same time, by protecting the non-disclosure of on-site information, the equipment ensures the standardization of the investigation process, provides true and complete original materials for subsequent physical evidence inspection and case identification, and improves the scientificity and legal effect of identification conclusions.
Application cases in the field of criminal investigation are practical: During the investigation of a homicide crime scene, several illegal UAVs attempted to conduct low-altitude photography of on-site details. Law enforcement personnel activated the equipment to directionally block the UAV's image transmission and control links, successfully forcing 3 UAVs to land, avoiding the leakage of on-site physical evidence information, and preserving a complete on-site environment for case identification; In the investigation of a drug case, the equipment accurately countered a UAV used for drug delivery. After forced landing, drugs and flight data were extracted from the aircraft, locking the ground operator and providing key physical evidence and identification basis for the case prosecution.
This equipment has the advantages of portability, concealment and precise countermeasure, making up for the lack of flexibility of large-scale countermeasure equipment. It not only protects the safety of criminal investigation scenes, but also provides reliable support for forensic identification, which is of great significance for improving the prevention and control capabilities of public security organs and strengthening the effectiveness of judicial evidence.
