The Letter aims to investigate the polarisation diversity for passive radar system. Digital television signal is used as the illuminator of opportunity in this experiment. Dual‐polarised Yagi‐Uda antennas have been independently designed as surveillance array antennas, which can receive horizontal (H) and vertical (V) polarisation simultaneously. The experimental results showed that the detection performance after polarisation processing depends on the difference between target polarisation state and interference polarisation state. The target detection performance will be improved if the technology of polarisation diversity is used.
