Embodiment Construction

[0081] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.

[0082] Divide the N personnel to be positioned into N-1 slave positioning personnel and 1 main positioning personnel. Each personnel carries a wireless receiving and transmitting device and communicates wirelessly. The ESPRIT method is used on the personnel receiving device to estimate the person who transmits the signal. The azimuth angle of , using the TOA method ranging technology to estimate the distance between the master and slave locators, the ID number of the master locator is m, 1≤m≤N, the ID number of the slave locator is i, i=1....N, and i≠ m.

[0083] Specifically include the following steps:

[0084] 1. Estimate the azimuth from the locator to the main locator

[0085] (1)t k Let S be the narrowband signal transmitted from the transmitting device of the positioning person i at any time,...

Abstract

The invention discloses a target joint networking positioning method based on relative navigation. The method comprises the steps of: (1), calculating the signal azimuth angle between a slave positioning person and a master positioning person; (2), calculating the distance between the slave positioning person and the master positioning person; (3), establishing a motion model and a relative stateequation based on target movement characteristics and joint networking positioning; (4), establishing a measurement equation based on the distance between the slave positioning person and the master positioning person and the signal azimuth angle; (5), calculating the position coordinate of the slave positioning person by adopting a Kalman filtering method; and (6), correcting the position of themaster positioning person by utilizing a joint networking positioning fusion method.

Description

technical field [0001] The invention belongs to the technical field of navigation, and in particular relates to a relative navigation-based target joint networking positioning method. Background technique [0002] In the complex environment of earthquake rescue, anti-terrorist operations, field search and rescue and other emergencies, operators often need to determine their current location, and communicate the location information to their companions and superior commanders in time, so that operators can grasp their own location status, Ensuring safety is also conducive to the commander's comprehensive understanding of the posture of all personnel and coordinating the next action plan. [0003] The traditional positioning method of observing the map environment through maps and compass is not so accurate, and the GPS module often cannot perform positioning functions because there is no signal. The solution has evolved from simple strapdown inertial navigation system naviga...
