Analysis of Chosen Results Based on Trials with Distributed and Collocated Passive-Active Radars

In the course of NATO SET-195 RTG work, a field trial with active and passive PCL sensors was conducted. The aim of the trial was to compare experimental results with DMPAR (Deployable Multiband Passive-Active Radar) simulations. Although DMPAR has been devised as collocated receiver system, trials were planned with collocated as well as distributed receiver configurations. Received data has shown that distributed configuration can and will fill in the gaps in the radar coverage created by terrain shadowing or multipath propagation. Also, the overall score in terms of Track Visibility (TV) and Probability of detection (Pd) have been improved in the collocated configuration. Results of the trials have confirmed operational properties of passive-active sensor proposed by SET-195. In this paper a short introduction summing up SET-152 and SET-195 work will be presented. Next, received results of collocated and distributed DMPAR will be shown, analyzed, compared and commented. Now, using those results one can analyze and project on operational characteristics of a distributed DMPAR.
