Radar Bullet is a special type of bullet the main use of radar bullet is to find land mines without setting foot on the ground. This consists of throwing a special bullet into the ground of a helicopter that could signal buried mines. Antipersonnel mines demand seventy new victims every day. This weapon is particularly cruel in children whose bodies that are smaller and closer to the burst are more likely to suffer serious harm. Severe disabilities and the psychological trauma following the explosion mean that these children will have to be cared for for many years.
PRINCIPLE OF RADAR
Radar is radio detection and range. Radar is a sensor. Radar makes use of radio waves to detect and locate objects. The purpose is to provide estimates of certain characteristics of your environment more commonly the presence, position and movement of aircraft, ships and other vehicles.
The radar operates by transmitting electromagnetic energy to the environment and detecting the energy reflected by the object. If a narrow beam of this energy is transmitted by the directive antenna, it is possible to estimate the direction from which the reflections and therefore the bearing of the object come. . The distance to the estimated reflecting object by measuring the period between radar pulse transmission and echo reception. At the beginning of the radar bullet the change of the medium by the waves must be taken into consideration.
The radars usually have the main parts, the transmitter antenna receiver, and the display.
The transmitter will transmit an electromagnetic signal through the antenna, which will reach the target and be reflected backwards. It calculates the same antenna and the time difference between the transmission of the signal and the reception, which will help to measure the distance of the objective from the radar.
