Remote detection positioning system and method for low-frequency radiation source target

The invention discloses a remote detection positioning system and method for a low-frequency radiation source target. The system comprises a conformal distributed antenna array, a plurality of receiving channels, an instantaneous frequency measurement unit, a digital signal processing module, a local oscillator, a signal sorting module, a signal receiving module, a signal conversion module, and a positioning method. The positioning method comprises the following steps: performing passive detection signal characteristic analysis; realizing signal sorting by utilizing correlation of radiation source parameters; identifying a sorting signal; carrying out passive positioning of a radiation source target; and carrying out target signal interference suppression. The system and the method are high in processing speed of information captured by a target, and are capable of finding and locking the target in a near-real-time manner; a target can be accurately found and tracked in a dynamic environment by adopting a mul
