  • Digital bi-static spread spectrum radar
    Patent number: 6031485
    Abstract: A bi-static spread spectrum digital radar including a transmitting antenna and a receiving antenna array separate from and positioned at a distance from the transmitting antenna. The transmitting antenna transmits a pseudo random digital signal as produced by a pseudo random digital signal generator. The receiving antenna array receives signals simultaneously and parallely as reflected from a target by the transmitting antenna. A plurality of analog-to-digital converters are connected respectively to each element of the receiving antenna array so as to convert the received analog signal into a digital signal. Digital beams are produced and directed to a set of digital receivers. A processor is provided so as to produce a digital output from the set of digital receivers.
