Abstract

The rapid development of quantum radar brings subversive challenges to radar countermeasures, the difficulty is reconnaissance. Aiming at the problems of quantum radar signal reception and passive direction finding at the present stage, this paper carried out research on quantum radar reconnaissance technology based on single photon measurement, proposed a passive direction finding method for quantum radar signal at the present stage, and verified the feasibility of the method through experiments and simulation calculation. This method solves the problem that the traditional passive direction finding technology is difficult to detect the quantum target signal, and can be effectively used for the detection and alarm of the quantum radar radiation source at this stage, which is of great significance in the fields of electronic countermeasures, environmental monitoring and space exploration.
