Abstract

The invention relates to passive radars, electric wave transmission and wireless communication, provides a broadband recognition passive radar facing a complicated heterogeneous wireless communication irradiation source in the future, and is suitable for the development tendency of a new method for searching by a new theory in the field of the passive radars at the present.. According to the technical scheme, a broadband recognition passive radar system architecture design method comprises the following steps of: taking a complicated heterogeneous wireless communication emission signal as a passive radar irradiation source; constructing a passive radar irradiation source library based on a future broadband wireless communication technology through machine learning; then supplying a multi-system and multi-standard compatible broadband recognition passive radar system architecture; and finally, dynamically selecting an optimal waveform as the passive radar irradiation source according to an environment feedback and prior information supplied by the irradiation source library, and realizing heterogeneous fusion and preferential work of a complicated heterogeneous irradiation source. The method is mainly applied to design and manufacturing of the passive radars.

Description

technical field [0001] The invention relates to passive radar, radio wave propagation and wireless communication. Specifically, it involves the architecture design method of broadband cognitive passive radar system. Background technique [0002] Passive radar technology is a model of special applications for military-civilian integration, and the combination of public systems and dedicated systems. It can effectively improve spectrum utilization efficiency, improve the environment, and co-exist. Passive radars are essentially bistatic (multistatic) radars that use external sources of radiation for target detection and tracking. It does not radiate electromagnetic waves itself, so it has good concealment and "four anti-" (anti-jamming, anti-low-altitude penetration, anti-radiation missile, anti-stealth) capabilities, and does not need spectrum allocation, which can effectively improve spectrum utilization Efficiency, and will not cause electromagnetic pollution to the envir...
