The Pareto rank algorithm for the division of the sub arrays for the phase array radar

With the continuous development of the electronic technology, there are many advanced technique that can be a threat to the traditional radar system in the modern war. The viability of radar systems is more and more depending on their anti-jamming capabilities. In other words, the radar is useless if it is not an anti-jamming radar. The viability of the radar system has been dramatically increased due to the use of the phase array radar. In phase array radar system, there are always thousands of antenna units. Each antenna unit has its own signal processing system. All the antenna units are put together in a plane according to some given order. In order to reduce the cost, we have to decrease the number of receive paths. Therefore, in this paper, we propose an approach to reduce the paths in phase array radar. The simulation results show that our proposed approach works well.
