Abstract:

The performance of a phased array radar could be optimized by allocating working parameters appropriately. In order to satisfy the requirement of low probability of intercept (LPI) for radar when using in the electronic countermine environment, some theoretic derivations are given according to LPI principle on two radiation power controlling strategies, which includes the minimum power strategy (MPS) and the minimum dwell-time strategy (MDS). Then a detecting performance optimization model aiming at detecting probability is put forward. And at the same time, the optimal radiation control scheme from the two power controlling strategies can be obtained.
