Abstract
Radio Detection and Ranging (RADAR) finds huge application in navigation to detect the speed velocity, angle, and range of the objects such as ships, aircraft, automobiles, missiles and it is also used for determining the environmental and geographical conditions. This vast application of Radar Engineering diverts the attention of the research community to work on this era. It has some issues and challenges such as low probability of target detection, the effect of noise is high, time complexity is more with poor resolution. Hence, for accurate detection ambiguity should be improved. In the current literature, various authors presented the models to increase the autocorrelation by using either compression techniques or by improving the merit factor. However, these approaches concentrate on static objects, have noise peaks which are above the threshold limit at various Doppler frequencies and can hide the targets easily. In this paper, Linear Block Code (LBC) has been used which improves the performance of radar and create clear windows at desired Doppler to give the accurate information about the moving target with respect to its speed and position. The 256-bit matrices code is designed and tested using MATLAB.
