Multi-sensor threat systems have been in service since the 1960s and add a level of complexity to any techniques that try to defeat them. Moore’s Law has increased the processing power of these threat systems exponentially over the past six decades to the point where fusing the information from each sensor to provide an enhanced target tracking capability is becoming computationally inexpensive and therefore more achievable. By fusing the information from multiple sensors using various wavelengths and frequencies, more sophisticated and multifaceted counter-countermeasures (CCMs) can be implemented to increase the probability of a successful target engagement. The rapidly evolving threat space requires new defeat mechanisms to be developed at an ever-increasing rate; therefore, this exploratory team aims to anticipate possible CCMs of future multi-sensor threats and identify possible approaches to defeating future multi-sensor threats.


The scientific objective of this exploratory team is to identify possible approaches to defeating multi-sensor threat systems that utilise the fusion of RF and EO/IR sensors to provide an enhanced target tracking capability, covering the air, maritime & land domains. In order to address the future multi-sensor threat, advanced sensor-fusion-based tracking algorithms will have to be conceptualised before any viable defeat concepts can be discussed. This will allow the exploratory team to get ahead of the current weapons development cycle and gain a significant advantage by anticipating possible CCMs of future multi-sensor threats. The exploratory team will then be able to develop a number of potential defeat concepts and look towards developing a way forward for simulating those concepts in operationally relevant scenarios. A key milestone of the exploratory team will be a report detailing a future approach to the development and evaluation of various potentially viable multi-sensor threat defeat concepts.


This activity will explore a broad range of potential solutions and will not be limited to the use of conventional countermeasure approaches. It is expected that existing, or developmental, EO/IR and RF countermeasure techniques will form a portion of the concept space; however other areas may also provide some utility. These include, but are not limited to: sensor damage; signature control; or modification and amendments to Tactics, Techniques & Procedures (TTPs). It is likely that the exploratory team will require a series of modelling tools that may include modifications to existing EO/IR and RF capabilities or look towards the development of a new model(s).
