This paper presents an analysis on the use of Long-Term Evolution-Railway (LTE-R) signals as illuminations of opportunity for the development of passive multistatic radar systems. This approach would allow the deployment of low-cost perimeter surveillance and monitoring systems along high-speed railway networks by using software defined radios (SDR) as multi-channel receiving nodes. To that end, taking into account the LTE-R specifications, the ambiguity function of LTE-R signals is analyzed in terms of range and Doppler resolution and sidelobe level. The associated signal processing based on delay-Doppler cross-correlation with the reconstructed reference signals is described. Finally, the detection range of the system for the detection of people, vehicles and small drones is estimated.
