description | The invention discloses a fixed target time domain positioning method of a bistatic radar, wherein the method comprises the steps of a step1, establishing a bistatic positioning system model; a step2, deriving the slant range progress of a single-scattering-point target; a step3, deriving a single-scattering-point target echo signal model after demodulation, and performing discretization on the single-scattering-point target echo signal model; a step4, constructing a three-dimensional signal matching matrix; and a step5, estimating the target position through calculation of an echo signal and the signal matching matrix, thereby realizing target positioning. The fixed target time domain positioning method has relatively high viability as a bistatic radar mode is used. The positioning precision of a proposed positioning system does not depend on signal bandwidth. A narrowband signal or a single-frequency continuous wave signal can be adopted. Low requirement for a transmitter and cost reduction of the whole system are realized. Relatively low calculation complexity of a positioning algorithm, high robustness and relatively high positioning precision are realized. Furthermore a plurality of target positions in an observation area can be simultaneously observed. |
