These techniques are strongly based on mathematics and specially on stochastic processes. Detecting a target in a noisy environment is a many folds sequential process. The signal processing chain only provides to the overall system boolean indicators stating the presence (or not) of targets inside the coverage area. It is part of the strategical operation of the radar. This paper mainly focuses on Design of Matched filter and generation of chirp Signal.

INTRODUCTION The use of electromagnetic waves in radar systems imposes some constraints on the overall performances. The basic concept of radars is to detect a target located at a distance denoted R by sending an electromagnetic wave through an antenna and measuring the time elapsed between the transmitted pulse and its received echo. According to optic/electromagnetic fundamental rules, this time denoted t 0 is directly proportional to the light velocity C[1] t 0 =   ……………….1 Equation (1) only gives information on the target range. Antenna theory states that the 3dBbeamwidth of an antenna is related to the carrier wavelength  and the size of the Antenna D in the given plane …………………………2
