Increase accuracy in range estimation of radar system

RADAR (Radio Wave Detection and Ranging) systems are widely used now days for detecting a target, obtaining its location along with direction and velocity of detected object. Most challenging part in RADAR system is to getting better accuracy in range estimation and also frequency jamming. In this paper, I have designed a radar system transmitter and receiver using direct sequence spread spectrum by MTALB Simulink for improving range accuracy as well as to avoid jamming. Mostly focus on spread spectrum because it has some advantages like accuracy of ranging, sensitivity of power estimation interference suppression etc.
