The invention provides a positioning method and apparatus of a single-emitting and moultiple-receiving passive radar random object, belonging to the technical field of radars. The method and device are used for solving the problems of low safety performance and high cost of present object positioning. The method comprises a step of determining an emitter and the coordinate positions of at least three non-collinear receivers in a set two-dimensional plane, wherein the at least three non-collinear receivers comprises an ith receiver, a step of determining the ith direction finding model of a random object in an ith single-emitting and moultiple-receiving channel through a formula (shown in the specification) according to the random object in a two dimensional plane and the ith single-emitting and moultiple-receiving channel formed by the emitter and the ith receiver, and a step of determining the positioning result of the random object in the two dimensional plane through a formula (shown in the specification) according to the ith direction finding model and at least three direction finding models determined by the at least three non-collinear receivers.
Description
technical field [0001] The invention belongs to the technical field of radar, and mainly relates to a method and a device for locating a random target of a single-shot multi-receive passive radar. Background technique [0002] Detecting, locating and tracking targets are the basic tasks of radar. Large scene fixed target positioning is an important content of battlefield situational awareness. In essence, the nature of target positioning is the same as that of radar imaging. When the resolution performance of the radar system can obtain target position information, it belongs to target positioning, and when the resolution performance can obtain target details, it belongs to radar imaging. The boundary between the two is not clear. The reason why there are few studies on target location is that SAR imaging technology is relatively mature. SAR imaging is mainly divided into two modes: spaceborne SAR and airborne SAR imaging. In the above two modes, spaceborne SAR imaging la...
