    Almost any freq. would work at that range depending of course on power level. What freq. are not allowed in India? Such information would help us help you. A standard X band transmitter(made in China of course) is used here in the states for traffic signal triggering in select areas where destroying pavement for inductive detectors is not possible.(historic sites specifically). A 'picture' is stored in memory of the empty zone and every few seconds another one is taken and compared to the one stored in memory. A large change in return signal when compared to the empty zone return is determined to represent a vehicle and traffic signals are changed to allow the vehicle to access the main lanes of cross traffic. simple concept but a very complicated circuit which uses a large micro and significant amounts of flash memory.
