Practical Application of Vehicle-mounted Long-distance Through-wall Detection System in Criminal Investigation and Forensic Identification
The Vehicle-mounted Long-distance Through-wall Detection System is a special non-line-of-sight perception and on-site reconnaissance equipment in the fields of criminal investigation technology and forensic identification. Based on low-frequency ultra-wideband MIMO radar technology, it can be mounted on various vehicle platforms to realize long-distance through-wall detection of human targets and indoor environments behind obstacles such as walls. Its core value lies in quickly obtaining information on the number, distribution and spatial structure of personnel in shielded areas without damaging the scene or making close contact, solving the pain points of difficult detection of hidden targets and easy damage to the scene in criminal investigation. It provides accurate and non-destructive technical support for on-site investigation, evidence fixation, case detection and forensic identification, helping to promote judicial justice and efficiency.
The core technical characteristics of the system are accurately adapted to the needs of criminal investigation and forensic identification: the long-distance and large-range scanning capability of 10-50 meters can quickly complete the investigation of the crime scene and surrounding shielded areas, improving reconnaissance efficiency; the strong penetration performance can penetrate common non-metallic building materials such as brick walls and gypsum boards, accurately identifying hidden human targets; the multi-target tracking and structure inversion functions can clearly grasp the target dynamics and on-site spatial layout, providing a basis for on-site reconstruction; the high environmental adaptability and remote display and control capabilities are suitable for various complex criminal investigation scenarios, ensuring concealed reconnaissance and real-time monitoring, avoiding the risk of exposure of investigators, and ensuring the compliance of the reconnaissance process, providing legal and effective data support for forensic identification.
Combined with criminal investigation practice and forensic identification cases, its application value is prominent: Case 1, in drug-related arrest and on-site investigation, the police mounted the system on a tactical vehicle, performed through-wall detection on the involved house 50 meters away, accurately grasped the number, distribution and house structure of drug addicts indoors, formulated a scientific arrest plan, and avoided damaging key physical evidence such as on-site drugs and drug-taking tools through close-range reconnaissance. The detection data of the system provided an important reference for the characterization of drug cases and the identification of involved personnel in forensic identification. Case 2, in the reconnaissance of a burglary, robbery and homicide case, the system restored the traces of personnel in the hidden area adjacent to the crime scene through through-wall detection, found the hiding traces left by the suspect, and inversed the house structure, assisting the police in restoring the suspect's escape route, and providing accurate technical basis for on-site reconstruction, trace identification and case characterization.
In summary, the system is suitable for scenarios such as criminal investigation of hidden targets, on-site investigation, hostage rescue, and post-disaster ruins search and rescue. It can realize non-destructive, long-distance and large-range non-line-of-sight detection, which not only improves the efficiency of criminal investigation and reconnaissance, but also effectively protects the integrity of the crime scene, provides accurate data and technical support for forensic identification, solves the technical problems of hidden area reconnaissance and on-site protection, and is an indispensable professional equipment in the fields of criminal investigation technology and forensic identification.
