N2 - With the development of science and technology, the Distributed Coherent Aperture Radar (DCAR) system, which can realize the energy synthesis of electromagnetic wave signals in space, has gradually become a research hotspot to satisfy the increasing requirements for coordinated detection. However, most existing studies consider the consistent state of each radar in the DCAR system, which is not instructive for radar systems with varying array sizes or under non-parallel beam pointing. In response to this issue, this paper constructs a corresponding signal model based on DCAR detection. Then, simulates and prototype experiments verify the multi-radar coherent synthesis gain under various differentiated conditions. Finally, the improvements of coherent synthesized signal-to-noise ratios (SNR) under multiple synergistic conditions are given, and the feasibility and achievability of differentiated distributed synergistic enhancement of perception are preliminarily verified.
