One of the most important problem in target tracking is Line Of Sight (LOS) rate estimation for using from PN (proportional navigation) guidance law. This paper deals on estimation of position and LOS rates of target with respect to the pursuer from available noisy RF seeker and tracker measurements. Due to many important for exact estimation on tracking problems must target position and Line O...

Proportional odds models are commonly used to model ordinal responses, but the proportional assumption may not hold in practice, leading biased inference. Tests such as score, Wald and likelihood ratio (LR) have been proposed evaluate based on without assumption. Brant has an independent binary model-based Wald-type test, Wolfe Gould extended idea propose LR-type test. This paper provides a bri...

This study presents analyses of guidance laws that involve non-monotonic convergence in heading error from a new perspective based on an advanced stability concept. Pure proportional navigation with range-varying gain is considered, and the condition to guarantee asymptotic collision course investigated while allowing exhibit patterns intermediate diversion. The extended criterion considered th...

with the continuous development of the industrialization process, the countries all over the world gradually appeared lack of agricultural labor force and aging phenomenon, which was especially prominent in developed countries. however the agricultural robot with high operating efficiency, high qualities of work will play an increasingly important role in future agricultural production. robot n...

localization of brain lesions and prevention of damage to vital structures are important in operation of brain pathologies. despite development of many techniques including angiography, mri, sonography, and frame base stereotaxy, a more accurate localizing technique is still needed (1, 2). a step forward to achieve this goal is to develop a navigation system. in this manuscript, we explained so...

In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

the problem of navigation among movable obstacles (namo) is to find a collision free path for a robot while the robot is able to manipulate and transfer some objects (if possible or needed) to clear its path toward the goal. namo is a np-complete problem and is in a class of motion planning problems that have dynamic environments. in this domain, an optimal plan for the robot can be defined wit...

For the application of autonomous guidance a quadrotor from confined undulant ground, terrain-following is major issue for flying at low altitude. This study has modified open-source autopilot based on integration multi-sensor receiver (a Global Navigation Satellite System (GNSS)), Lidar-lite laser-range-finder device), barometer and low-cost inertial navigation system (INS)). These automatical...

We use Reinforcement Meta-Learning to optimize an adaptive integrated guidance, navigation, and control system suitable for exoatmospheric interception of a maneuvering target. The maps observations consisting strapdown seeker angles rate gyro measurements directly thruster on-off commands. Using high fidelity six degree-of-freedom simulator, we demonstrate that the optimized policy can adapt p...
