The traffic RADAR is being developed operating at 24GHz to monitor the road traffic. The phased array system, comprising of 2D array at both Tx and Rx with their respective front ends are being developed to have a high performance MIMO RADAR that can be used in all weather and lightning conditions. The RADAR must have a high gain and very low SLLs with a reasonable beam width to cover the wide roads. It is a continuous wave Doppler RADAR that can measure the position and the velocity of a vehicle by employing beam forming and it can differentiate among different vehicles for the traffic management.
