Latest Patents

Chen Ji holds a patent for a "Coherent microwave photonics radar detection method and system based on injection locking frequency multiplication." This patent discloses a method that utilizes a baseband signal to modulate an optical carrier, generating a modulated optical signal with multiple high-order sidebands. The modulated optical signal is then divided into two paths, which are injected into two slave lasers for high-order sideband injection locking. This process results in two locked sideband optical signals. By combining and splitting these signals, the radar transmitting signal and receiving optical signal can be obtained through photo-detection and electro-optic modulation. The coherent detection of the receiving optical signal allows for the extraction of target information from the intermediate frequency signal using radar algorithms.
