Open Access research that helps to deliver "better medicines"...

Strathprints makes available scholarly Open Access content by the Strathclyde Institute of Pharmacy and Biomedical Sciences (SIPBS), a major research centre in Scotland and amongst the UK's top schools of pharmacy.

Research at SIPBS includes the "New medicines", "Better medicines" and "Better use of medicines" research groups. Together their research explores multidisciplinary approaches to improve understanding of fundamental bioscience and identify novel therapeutic targets with the aim of developing therapeutic interventions, investigation of the development and manufacture of drug substances and products, and harnessing Scotland's rich health informatics datasets to inform stratified medicine approaches and investigate the impact of public health interventions.

Abstract

The challenge of ballistic missiles classification is getting greater importance in last years. In fact, since the antimissile defence systems have generally a limited number of interceptors, it is important to distinguish between warheads and confusing objects that the missile releases during its flight, in order to maximize the interception success ratio. For this aim, a novel micro-Doppler based classification technique is presented in this paper characterized by the employment of Krawtchouk moments. Since the evaluation of the latter requires a low computational time, the proposed approach is suitable for real time applications. Finally, a comparison with the 2-dimensional Gabor filter based approach is described by testing both the techniques on real radar data.
