This annual report gives an account of the activities carried out and the results produced in the first year of the three-year Armed Forces' project Battlefield Surveillance Radar. The project involves a further development of the competence and technique platform established by FOI through previous efforts established in the research areas of Wall Penetrating Radar and Radar for Seeing behind Corners. The project is focused on the phenomenological and technical study, evaluation and development of methods, signal processing and system solutions for both Doppler-based and imaging wall-penetrating radar systems. The project participates in the NATO group Advancing Sensing through the Walls Technologies (2009-2013), including Sweden, US, Canada, France, Norway and Turkey. The group studies methods and techniques that increase the ability of detecting, tracking and imaging primarily humans behind walls. In the group, FOI is responsible for following and documentation of the current state of research with respect to radar for seeing behind corners. In order to improve detection performance for human targets we are investigating the possibility to use polarimetric wave-forms. Fully polarimetric imaging measurements that have been carried out of a human behind a wooden wall and a light concrete wall provide base data for the project research. A contrast optimization of the human-to-background ratio has produced a positive result for the studied wall type, a thin wooden cabin wall. Similar results may be expected for inner walls of plasterboard and chipboard. This year's measurements with light concrete walls pointed to insufficient power of the radar equipment used. The obtained results indicate that a natural continuation is to study the combination of polarimetry and Doppler methodology, i.e. Doppler polarimetry. The method of radar detection of human motion behind corners, launched by FOI, has been further developed. We have this year initiated work on studying the possibility to improve the positioning of a moving target by using antenna solutions with narrower lobes. The method is based on knowledge of the geometry of the actual environment, the antenna position, and the direction of the antenna lobe in time. Preliminary results are positive. We have in a study investigated various methods to increase the resolution of an urban target within the field of view of a radar. A way to effect this is to exploit a priori knowledge about an urban scene (geometry, material). Calculations made point to the possibility of substantially increasing the resolution of a battle-field radar if one has very good knowledge of the scattering properties of the scene. However, in the case of a quick deployment of a radar this possibility is deemed limited. A second interesting method, the Cetin-method, can give an increase of the resolution of low-resolution range profiles. A third technique, so-called MIMO radar, also displays great potential for increasing the positioning accuracy of a target in the urban scenario. Within the project frame, FOI is establishing deepened system competence, where we have developed an evaluation methodology of our own for wall-penetrating systems. Thereby, we contribute to being able to better support the Swedish Materiel Administration and the Armed Forces in future evaluation assignments. In 2012, earlier performed system tests were supplemented with tests of the English system Prism 200. Because of earlier concluded security agreements with the manufacturers, the results of the tests are presented in a separate restricted report.
