field-programmable gate array is a semiconductor device containing programmable logic components called logic blocks, and programmable interconnects. Logic blocks can be programmed to perform the function of basic logic gates such as AND, and XOR, or more complex combinational functions such as decoders or mathematical functions. In most FPGAs, the logic blocks also include memory elements, which may be simple flip-flops or more complete blocks of memory. A hierarchy of programmable interconnects allows logic blocks to be interconnected as ne ....etc

Adaptive active phased array radars are seen as the vehicle to address the current requirements for true ?multifunction? radars systems. Their ability to adapt to the enviournment and schedule their tasks in real time allows them to operate with performance levels well above those that can be achieved from the conventional radars. Their ability to make effective use of all the available RF power and to minimize RF losses also makes them a good candidate for future very long range radars. ....etc

Abstract : A study with the goal of contributing to the development of adaptive phased array radar techniques is presented. Adaptive phased array radar is concerned with modification by closed loop control of the radar in response to a change of radar environment such that performance is improved with respect to performance before modification. This study has been concerned with selection of a quantitative measure of radar system performance and relating this measure of performance to control of phased array radar parameters. Modeling of the g ....etc

A field-programmable gate array (FPGA) is an integrated circuit designed to be configured by the customer or designer after manufacturing.FPGAs can be used to implement any logical function that an ASIC could perform. The ability to update the functionality after shipping,FPGAs contain programmable logic components called logic blocks, and a hierarchy of reconfigurable interconnects that allow the blocks to be wired together”somewhat like a one-chip programmable breadboard,

INTRODUCTION

RAIN (also called channel bonding, redundant array of independent nodes, reliable array of independent nodes, or random array of independent nodes) is a cluster of nodes connected in a network topology with multiple interfaces and redundant storage. RAIN is used to increase fault tolerance. It is an implementation of RAID across nodes instead of across disk arrays.
RAIN can provide fully automated data recovery in a local area network (LAN) or wide area network (WAN) even if multiple nodes fail. A browser-based, centralized, s ....etc

INTRODUCTION
The radar systems have been changing on the account of the requirements caused by:- Increase in the number of wanted and unwanted targets. Reduction in target size. Need to adapt a greater no. of electronic counter measures.
CATEGORIES OF RADAR
Two Categories:-
1. Single-function radars.
2. Multi function radar (passive phased array).
SINGLE FUNCTION RADAR
Has fixed antenna with centralized transmitters.
Eg:1) Surveillance radar
2) Tracking radar
MULTI-FUNCTION RADAR
Passive phased array:- use ....etc
