We present lessons learned in USAR research within the framework of the German research project I-LOV. After three years of development first field tests have been carried out by professionals such as the Rapid Deployment Unit for Salvage Operations Abroad (SEEBA). We present results from evaluating search teams in simulated USAR scenarios equipped with newly developed technical search means and digital data input terminals developed in the I- LOV project. In particular, the “bioradarâ€, a ground-penetrating radar system for the detection of humanoid movements, a semi-active video probe for rubble pile exploration of more than 10 m length, and the decision support system FRIEDAA were evaluated and compared with conventional search methods. Results of this evaluation indicate that the developed technologies foster advantages in USAR, which are discussed in this paper.
