In this paper, we propose a nonlinear guidance law for missiles against maneuvering targets. First, we derive the equations of motion described in the line-of-sight reference frame and then we define the equilibrium subspace of the nonlinear system to guarantee target interception within a finite time. Using Sontag’s formula, we derive a nonlinear guidance law that always delivers the state to ...

Missile pose estimation in terminal guidance refers to the technique of estimating missile position and attitude by matching seeker images with pre stored reference images during the terminal phase of missile flight. This paper presents a method for estimating the position and orientation of the missile with respect to a known object using point correspondences between seeker and reference imag...

in this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. generally the lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. because of uncertainties and undesired factors, the nominal position and velocity obtained by lambert technique need to be followed in actual flight. ...

In an earlier study, presented at the 3 rd EUCASS [1], an innovative guidance strategy was outlined by integrating the design of a multiple model adaptive estimator and a differential game based guidance law. Such strategy indicated two potential breakthroughs in the interception of randomly maneuvering targets in Ballistic Missile Defense. Further studies indicated that while the differential ...

∗ Both authors are visiting professors at Macedonian Military Academy, and have significant contribution in teaching/research activities in the field of intelligent missile systems Abstract. We have developed a simulation model of homing-guided anti-aircraft or surface-to air (SA) missiles SAM, suitable for research, development and testing of different guidance and control laws, obtained from ...

Many countries including India use the Russian made SAM-3 (Pechora) surface-to-air missile (SAM) weapon systems to protect their strategic and tactical infrastructure. The mathematical computations done in this paper, conclusively proves that SA-125 low-blow tracking radar of Pechora is vulnerable to jamming. A project was undertaken to overcome the jamming vulnerability of Pechora aiming to de...

In this paper, an adaptive fuzzy neural network (FNN) controller is proposed for missile guidance. The objective is for one defending missile (DM) to intercept an attacking missile (AM) in air battle scenario. The adaptive FNN controller is adopted to force the DM toward the AM under the existence of disturbance, and a monitoring controller is also designed to reduce the error between FNN contr...

This paper examines the proposed integrated backstepping design of missile guidance and control to the engagement of manoeuvring targets. To control engagement geometry, impact-anglecontrol guidance (IAGC) is analysed in two dimensional geometry. The integrated backstepping design with disturbance observer is then developed and interpreted in view of stability and robustness. The performance of...
