Description

Traditional opportunity signals of passive radar are FM radio and TV broadcast stations. But these occur at long wavelengths, offering range resolution and detection capabilities insufficient for small object detection such as UAVs.
4G-LTE base stations (BS) appear as ubiquitous opportunity signals in urban and even rural areas, with higher carrier frequencies, promising precision improvements.
But these signals operate based on user demand, not as a continuous broadcast, on top of using an orthogonal frequency division multiplexing (OFDM) waveform, known for its high Peak-to-average Power Ratio (PAPR), both of which could impede on availability and reliability of passive radar detections.
In this work, we present a GNU Radio based data gathering system to evaluate the power variations of signal broadcast by operating BS at different time scales, and study the behaviour of BS from multiple mobile operators in the wild, informing future 4G based passive radar designs.
