Generation of Control Signals for A Transmitter in Troop Level Radar of Akash Missile System

Abstract

In the pulsed radar transmitter system the amount of the Radio Frequency (RF) signal to be transmitted by the Travelling wave tube (TWT) plays an important in order to track the enemy targets. Therefore the pulse generated has to be fed to the control grid of TWT which in turn determines the power required for the transmission.Here, we are generating and controlling the 32 combination of pulses which enables to gets the information of targets distance using 8051 Microcontroller with LCD and keypad interface. Transmitter control signals (Grid pulses) generation to perform stand-alone test of transmitterused in TLR (Troop level radar) of Akash Missile System. Akash Missile System is a part of Indian Defence and TLR is tracking radar of this system, TWT (Travelling Wave Tube) based transmitter is used in TLR. This interface is used in our project so as to make it cost effective and to control the required signals manually. The pulses thus generated are fed to the Differential Line Driver (DLD) circuit as the radar consists of differential receiver. DLD helps to carry the RF signal in a parallel line Transmission line with no noise addition.
