Cruise Missile Mission Planning Using Genetic Algorithm

Abstract: Mission planning is a critical stage in launching a cruise missile against highly defended targets It is required to generate an optimal trajectory during combat scenario (real time) just before launch Typically, this type of engagement is carried by cruise missiles flying at low altitudes below 100 m In addition to air defense, terrain features also need to be avoided by following certain way-points This study investigates use of genetic algorithms (GA) as an optimization procedure in the flight trajectory planner to be used in the real-time environment

Hybrid Architecture For Real Time Image Registration

Abstract: This paper deals with the real time implementation of an image registration algorithm, for an application onboard a flight vehicle, where there are limitations on system power and space, in addition to the processing time constraint. Two images must be registered to find the similarity between them or to find the object motion in a scene. Real time in this application means an update time of 1/30th of a second i.e., at TV frame rate. The direct method using the normalised correlation function is chosen for implementation considering both the performance and the computational complexity. A hybrid approach using dedicated hardware for computation intensive part of the algorithm and a microprocessor based subsystem for other functions is adopted as a compromise between flexibility and efficiency. To meet the time constraint parallel pipelined architecture is used. To meet the low power requirement mostly CMOS devices are used. To meet the space constraint specific integrated circuits are being planned. A specific example of implementation is given.

Distributed real-time Radar Simulation Test bed for qualification of mission critical systems

Abstract: Testing of radar based systems is an arduous exercise and it is essential to develop a real-time radar simulator for testing such systems. However, as radar simulation test bed demands more computational resources to meet the real-time deadlines, it turns out to be more complicated than the system being tested. Distributed computing provides an elegant solution for its need of high computational resources. However, it calls for data, event and time synchronization among the processors. In this paper, we present a successful realization of distributed real-time Radar Simulation Test bed for testing mission critical systems.
