          Abstract

          By the synthesis of multi-radar electromagnetic wave space energy, Distributed Aperture Coherencesynthetic Radar (DACR) achieves long-range power detection via multi-radar airspace expansion to realize high-precision target angle measurement. DACR has the advantages of strong survival ability, a high cost- effectiveness ratio, high angular accuracy, strong expandability, and easy realization. In this article, we analyze the joint antenna gain of a non-directional multi-point source and, given the theoretical derivation and simulation analysis, we establish a distributed-array-antenna geometric model, analyze the joint antenna pattern and gain, respectively, and determine that the joint antenna gain is approximately equal to the unit radar number and the unit radar gain product. Lastly, we perform a joint antenna gain simulation using HFSS software to further verify the joint antenna gain results.
