Abstract: This paper addresses the development efforts towards spread spectrum digital beam forming vehicular radar. Lot of limitation for Conventional radar system; to overcome this problem we are using CSWAP technique for the design of fully integrated Hybrid DBF vehicular Radar. So planar array structure based microstrip antenna which is digitally controlled by DSP or FPGA board is the important part of this work. Lot of works carried out by us that is Antenna radiation pattern, element pattern, power pattern, array factor, antenna e-scanning and beam formation, digital beam formation using different combination of elemental patch and side lobe reduction using different windowing techniques is the major part of this work .The car fitted at the front with single 77GHz will take joint decision of LRR as well as SRR [1]. So in the channel lot of polluted signal like interference, clutter noise arises in the receiver portion of this radar to avoid this proper choice of waveform is very important part also of the SSDBF vehicular Radar at the transmitter side .We have tested different orthogonal codes like Barker, Frank,Gold,P1,P2,P3,Px. and their performance analysis.
