Over-the-air deramping for multistatic perimeter surveillance

Abstract

This paper explores the use of an over-the-air deramping (OTAD) system as a solution for perimeter surveillance. Over-the-air deramping is a technique for wirelessly synchronising distributed passive FMCW radar nodes to a dual-frequency master FMCW transmitter node. Such a system gives the benefits of simultaneous monostatic and multistatic measurements for improved clutter resilience, and multiple looks at a target for reduced susceptibility to signal fading due to target scintillation. To prove the latter, a simultaneous monostatic and OTAD bistatic node were set up with a 5 m baseline, and a walking person was measured. The results show that signal fading occurs in both the monostatic and the bistatic node, but rarely at the same time. Hence, combining the measurements from the two nodes gives a consistent response from the target. This demonstrates the benefit of an OTAD system for a robust perimeter surveillance system.

“…The radar uses a FMCW architecture operating at C-band with a central frequency of 5.8 GHz. This system was manufactured using commercial off-the-shelf (COTS) surface mount components on an in-house designed PCB [38], [39]. A basic block diagram of the system design can be seen in Figure 1 along with the RF parameters in Table 1.…”
