设备基于蜂窝移动通信协议分析与定向射频测向技术，全面覆盖国内主流 2G/3G/4G 全通信频段，高灵敏度接收模块可捕获目标设备待机状态下与基站交互的微弱信令信号，通过定向天线阵列与精准测向算法完成信号来波方向判定，引导操作人员逐步逼近发射源，实现从区域扫描到精准定位的全流程。设备采用人机工程学手持设计，单兵即可独立操作，无需复杂布设，宽温宽湿环境适应性强，具备可调探测门限与优异抗干扰能力，解决了传统设备无法侦测待机状态网络型窃密设备、定位精度低、复杂环境抗干扰能力弱、部署繁琐的行业痛点。
在刑侦与司法鉴定实战中，设备核心应用覆盖四大领域：一是侦查行动技侦环境安全反制，完成重大专案会议、秘密侦查行动前的场所与车辆安全排查，定位网络型窃听装置、非法定位跟踪器，保障行动绝对机密；二是侵犯公民个人信息案件侦办，现场快速定位起获涉案的远程窃听窃照、非法跟踪设备，固定核心电子物证，支撑案件定罪与司法诉讼；三是重大案件嫌疑人搜查与管控，在嫌疑人住所、窝点搜查中，发现隐蔽安装的监控、报警装置，完善案件证据链；四是重要场所与涉密会议安保，完成党政机关、涉外场所、核心涉密会议的会前保密检查，筑牢电子安防屏障。
实战应用案例：1. 某非法跟踪定位刑事案件，受害人长期被不明人员跟踪骚扰，传统射频探测器未发现异常，技术人员使用本设备对受害人车辆进行全面扫描，精准定位隐藏在车辆底盘内、处于待机状态的 4G 网络 GPS 跟踪器，当场查获涉案器材，顺线抓获犯罪嫌疑人，为案件侦破提供了核心支撑；2. 某重大涉密专案侦查前，技术人员使用设备对专案指挥部、涉案人员秘密谈话场所进行地毯式扫描，成功定位 2 枚隐藏在墙体内部、利用公共网络远程回传音频的窃听装置，彻底消除泄密风险，保障了专案侦查行动的绝对安全。
本设备为一线刑侦技侦人员提供了复杂电磁环境下主动发现、精准打击隐蔽电子威胁的有效手段，其专项侦测能力与高精度定位特性，为电子物证固定、司法诉讼提供了坚实的技术支撑，是构建现代化主动式技术侦查与安全防护体系的关键装备。
Application Introduction of the Handheld Individual Soldier Radio Positioner in Criminal Investigation and Forensic Identification
The Handheld Individual Soldier Radio Positioner is a portable core technical surveillance countermeasures (TSCM) equipment integrating wide-band signal detection and high-precision directional positioning functions. It is specially developed for criminal investigation, technical security, and on-site investigation of electronic evidence. It serves as key criminal technical equipment for implementing technical countermeasures, detecting concealed eavesdropping/surveillance devices and illegal positioning trackers, and maintaining the confidentiality of investigation operations. It can accurately detect and locate concealed electronic devices based on public mobile communication networks, filling the technical gap of conventional detectors in detecting network-based eavesdropping devices in standby state.
Based on cellular mobile communication protocol analysis and directional radio frequency (RF) direction finding technology, this equipment fully covers all mainstream domestic 2G/3G/4G communication frequency bands. Its high-sensitivity receiving module can capture weak signaling signals exchanged between the target device in standby state and the base station. Through the directional antenna array and accurate direction finding algorithm, it determines the direction of arrival of the signal, guides the operator to gradually approach the transmission source, and realizes the whole process from area scanning to accurate positioning. The equipment adopts an ergonomic handheld design, which can be independently operated by a single soldier without complex deployment. It has strong adaptability to wide temperature and humidity environments, with adjustable detection threshold and excellent anti-interference capability. It addresses the industry pain points of conventional equipment, such as inability to detect network-based eavesdropping devices in standby state, low positioning accuracy, weak anti-interference capability in complex environments, and cumbersome deployment.
In the practical operation of criminal investigation and forensic identification, the core applications of the equipment cover four major areas:
- TSCM and security countermeasures for investigation operations: completing security inspections of premises and vehicles before major special case meetings and covert investigation operations, locating network-based eavesdropping devices and illegal positioning trackers, and ensuring the absolute confidentiality of operations;
- Investigation of cases involving infringement of citizens' personal information: quickly locating and seizing the involved remote eavesdropping/surveillance devices and illegal tracking equipment at the scene, fixing core electronic physical evidence, and supporting the conviction and judicial proceedings of the case;
- Search and control of suspects in major cases: detecting concealed monitoring and alarm devices installed in the suspect's residence and den during the search, and completing the evidence chain of the case;
- Security of important premises and confidential meetings: completing pre-meeting confidentiality inspections of party and government organs, foreign-related premises, and core confidential meetings, and building an electronic security barrier.
Practical Forensic Application Cases:
- In a criminal case of illegal tracking and positioning, the victim was followed and harassed by unknown persons for a long time, and no abnormality was found by conventional RF detectors. Technicians used this equipment to conduct a comprehensive scan of the victim's vehicle, accurately located the 4G network GPS tracker in standby state hidden in the chassis of the vehicle, seized the involved equipment on the spot, arrested the suspect along the line, and provided core support for the detection of the case.
- Before the investigation of a major confidential special case, technicians used this equipment to conduct a carpet scan of the special case headquarters and the secret conversation place of the involved persons, successfully located 2 eavesdropping devices hidden inside the wall that used the public network to transmit audio remotely, completely eliminated the risk of information leakage, and ensured the absolute safety of the special case investigation operation.
This equipment provides frontline criminal investigation and technical reconnaissance personnel with an effective means to actively detect and accurately strike concealed electronic threats in complex electromagnetic environments. Its special detection capability and high-precision positioning feature provide solid technical support for the fixation of electronic physical evidence and judicial proceedings, and it is key equipment for building a modern and active technical investigation and security protection system.
