LTE-BASED PASSIVE FORWARD SCATTERING RADAR FOR HUMAN DETECTION WITH NEMO HANDY SUPPORT

Abstract

A radar used for radar detection includes a setup of a transmitter and a receiver, which may identify any human or animal object that travels between the receiver and the source of illuminator of opportunity via the system. The targets in this study were mainly human, comparable to the situation where intruders enter the country illegally, and by distinguishing between human sizes, the detection can be conducted, which is focused on the body dimension. There have been many cases such as kidnapping at the border in Lahad Datu, Sabah. In order to improve border protection, the passive forward scattering radar system could support the research investigation on the transmitting strength of 4G Long-Term Evolution (LTE) networks that concentrated on Reference Signal Received Quality (RSRQ) and Reference Signal Received Power (RSRP) parameters using Nemo Handy to measure the signal strength and validate the findings of human detection using the setup of this radar system. In addition, this radar system was employed to detect any object that crossed between a commercial transmitter and receiver with a bistatic angle of about 180 ̊ which is forward scatter and produced a Doppler signature. This investigation was carried out utilizing the 1.8 GHz LTE frequency in three separate locations: Batu Laut (Selangor), Port Dickson (Negeri Sembilan), and Taman Suria (UiTM, Selangor). The receiver's data is then extracted and analyzed using MATLAB software. There are four period ranges, namely morning, night, evening and afternoon in this study. Conclusively, Nemo Handy can describe the best time range to support passive forward scattering radar system to provide the best period for human detection. In addition, this system can contribute to many areas such as border or street, to detect human detection and for some reason as protection, security and research.
