Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] In the embodiment of the present invention, the missile-borne bistatic synthetic aperture radar (SAR) in the missile-borne dual / multistatic radar is taken as an example, and the positioning principle of the missile-borne dual / multistatic radar is the same as that of the missile-borne bistatic SAR.

[0047] refer to figure 1 , the implementation steps of the present invention are further described in detail.

[0048] Step 1, establish a three-dimensional imaging coordinate system.

[0049] When the three-dimensional imaging coordinate system is established, the sub-satellite point of the receiving radar in the missile-borne bistatic SAR is used as the coordinate origin, the flight direction of the receiving radar is used as the positive direction of the Y axis, and the vertical upward direction perpendicular to the ground is us...

Abstract

The invention discloses a missile body analysis and positioning method based on a double / multi-base radar. The implementation scheme comprises the following specific steps: 1) establishing a three-dimensional imaging coordinate system; 2) acquiring an image of a missile-borne double / multi-base radar ground distance plane; 3) obtaining matching points in the missile-borne double / multi-base radar ground distance plane image; 4) calculating the total number of distance units of each matching point; 5) calculating the bistatic distance sum of the missile-borne bistatic / multistatic radar; 6) establishing a missile-borne double / multi-base radar nonlinear positioning equation set; 7) solving the position coordinates of the receiving radar in the missile-borne dual / multi-base radar; and 8) determine the position coordinates of the receiving radar in the missile-borne dual / multi-base radar. The missile-borne double / multi-base radar positioning method is used for positioning the receiving radarin the missile-borne double / multi-base radar in the missile terminal guidance stage, and has the advantages of being high in positioning precision, wide in application range and good in robustness.

Description

technical field [0001] The invention belongs to the field of radar technology, and further relates to a dual / multi-base radar projectile analysis and positioning method in the field of radar signal processing technology. The invention can be used to realize the precise positioning of the receiving radar seeker when striking the dual / multi-base radar target. Background technique [0002] The missile-borne dual / multi-base radar can realize two-dimensional high-resolution imaging of the target area directly in front of the receiving radar, breaking the defect that the missile-borne single-base radar cannot look forward to imaging, and expanding the application of the radar imaging system in the terminal guidance stage. Dual / multi-base radar guidance technology has been widely used in the field of positioning. [0003] Xu Yushi proposed a bistatic radar target positioning method based on the range-Doppler equation in his paper "Bistatic (Multistatic) Synthetic Aperture Radar Po...
