Cooperative guidance of seeker-less missile considering localization error

Design a Guidance Law Considering Approximation of Missile Control Loop Dynamics Using Adaptive Back-Stepping Theory

In this paper, a new guidance law is designed to improve the performance of a homing missiles guidance system in terminal phase. For this purpose first of all, the two dimensions equations of motion are formulated, then the approximation dynamic of missile control loop is added to these equations which are nonlinear whit unmatched uncertainty. Then, a new adaptive back-stepping method is develo...

Optical Performance Anal Ysis of Standard Missile Blockiy a Seeker

The flight environment of the Standard Missile, Block IV A interceptor involves high speeds that place severe aerodynamic and aero-thermalloads on the missile optical window and sensor. The supersonic flow over the missile produces aero-optical effects that can degrade IR seeker performance. This report summarizes an analysis of aero-optical aberrations due to shock front and shear layer densit...

Guidance Law Evaluation for Missile Guidance Systems

In missile guidance system, to reduce the interception “miss distance,” it is important to choose a suitable guidance law and navigation constant. This paper investigates and compares the system behavior of guidance laws under different navigation constants. Based on use of the adjoint technique, miss distance sensitivity analyses which consider the system noise, target step maneuver, initial h...

The Cruise Missile Guidance Problem

In airframe technology, designs have become progressively more compact, to accommodate internal and external carriage by aircraft, launch tubes on warships or torpedo tubes in submarines. Propulsion has evolved from simple pulse jets, through turbojets and liquid propellant rockets or ramjets to the current mix of: turbojets for subsonic tactical cruise missiles, turbofans for subsonic strategi...
