Landmines and unexploded ordnance


INTRODUCTION

Landmines and unexploded ordnance (UXO) are a legacy of war, insurrection, and guerilla activity. Landmines kill and maim approximately 26,000 people annually. In Cambodia, whole areas of arable land cannot be farmed due to the threat of landmines. United Nations relief operations are made more difficult and dangerous due to the mining of roads. Current demining techniques are heavily reliant on metal detectors and prodders.

ABSTRACT

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.

LANDMINES

INTRODUCTION
One of the most deadly legacies of the 20th century is the use of landmines in warfare. Anti-personnel landmines continue to have tragic, unintended consequences years after a battle and even the entire war has ended. As time passes, the location of landmines is often forgotten, even by those who planted them. These mines continue to be functional for many decades, cau ....etc

More Info About active adaptive phassed array radars

a phased array is a group of antennas in which the relative phases of the respective signals feeding the antennas are varied in such a way that the effective radiation pattern of the array is reinforced in a desired direction and suppressed in undesired directions. Phased array transmission was originally developed in 1905 by Nobel Laureate Karl Ferdinand Braun who demonstrated enhanced transmission of radio waves in one direction. During World War II, Nobel Laureate Luis Alvarez us ....etc

MILITARY RADARS



INTRODUCTION

Military radar should be an early warning, altering along with weapon control functions. It is specially designed to be highly mobile and should be such that it can be deployed within minutes.
Military radar minimizes mutual interference of tasks of both air defenders and friendly air space users. This will result in an increased effectiveness of the combined combat

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
