Detection performance and configuration of Network Radar: A study based upon symmetry cross entropy

Network Radar realizes the integration of the radar and radar countermeasures; it is a new trend of radar and radar countermeasures system. At first, it introduces the concept and some research results of the configuration of Network Radar. In succession, the CE (cross entropy) theory is utilized to evaluate the detection performance of Network Radar. We investigate the CE and put forward the concept of SCE (symmetry cross entropy) to compensate its inability to meet symmetry, and then prove in theory that it is a distance measure; thus the new evaluation model comes into existence which adopts the SCE as an evaluation criterion. By means of the simulations of the detection performance and configuration of Network Radar, The results prove that the method we have proposed is effective and feasible.
