ABSTRACT: Radar is an object detection system which uses electromagnetic waves specifically radio waves — to determine the range, altitude, direction, or speed of both moving and fixed objects. The radar dish, or antenna (parabolic), transmits pulses of radio waves or microwaves which bounce off any object in their path. The object returns a tiny part of the wave's energy to a dish or antenna which is usually located at the same site as the transmitter. This project is used to identify the direction of the target from which it is coming and position of the object. This project uses AT89S52 Microcontroller which is interfaced with Radar Target Identifier system has an array of IR sensor pairs. These IR sensors are keeping track with the target in all the directions. If the target is found to be moved in any direction and then it gives a control signal to the microcontroller and the status is displayed on the LCD for user identification. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.

INTRODUCTION: The main objective of this project is identifying the radar target direction with remote station alert system. Radar signal containing selected target simulations modulates an optical, infrared signal, in accordance with the selected target simulations. Radar target system is provided with selectively direct modulated IR radiation onto selected areas of an RF (Radar Frequency) array. Radar target identifier is selected with areas of the RF array function to add target angular simulations and target space position and scintillations to the other simulations contained in the radar signal. The IR radiation is converted to a radar frequency signal in the RF array and is transmitted to the radar test system. This Project basically has two phases: Parabolic antenna and ARM Processor (LPC2148).Firstly, a parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The main advantage of a parabolic antenna is that it has high directivity. Secondly, The LPC2148 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with real- time emulation and embedded trace support, that combine the microcontroller with embedded high-speed flash memory ranging from 32 KB to 512 KB. A 128-bit wide memory interface and unique accelerator architecture enable 32-bit code execution at the maximum clock rate.
