Experimentation of an adaptive and autonomous RF signalling strategy for detection

Abstract

In this paper we discuss a straightforward signalling strategy for target detection and shared spectrum usage. We further combine additional practical concerns such as waveform modulus and extended target matched illumination to improve detection performance in dynamic interference environments. The impetus for the straightforward, yet suboptimal, strategy are the low cost drivers for small sensing platforms, such as small unmanned aerial systems (SUAS). Herein, we discuss a complete strategy and algorithm for sensing the environment, interrogating the target response and adapting the transmitted waveform to avoid the primary users while putting more energy on target than previous non-adaptive strategies. We give simulation results and initial experimental results to corroborate the theoretical and simulated findings.

Fast Fully Adaptive Signalling for Target Matching

“…We consider a single target whose range profile response evolves over time. Preliminary results were first reported in [13]. The approach taken trades some level of performance against a reduced computational load, with the aim of power and weight savings and reducing the computational burden of the adaptive algorithm.…”
