Futuristic transportation systems would be requiring more effective sensing system that are not only cost effective but also more efficient in sensing multiple targets while acquiring minimal area and utilizing low input power. To achieve that, frequency modulated continuous wave (FMCW) based Photonic Radar is proposed. For multiple targets detection, wavelength division multiplexing (WDM) scheme is used in conjugation with polarization division multiplexing (PDM) scheme. Impact of varying bandwidth is analyzed upon the performance of the proposed system using numerical simulations. The system is simulated for detecting and ranging over 100 meters by analyzing received echoes and verifying the range frequency with theoretically calculated values while effective operation is measured in terms of received power under varying level of attenuation up to 75 dB/Km under rain and fog conditions. Lastly, the system is replicated for range resolution with four varying operational bandwidths from 600 MHz to 4 GHz.
