  • Patent number: 10794988
    Abstract: A method of implementing spread spectrum techniques in an automotive radar with wireless communication capabilities enables an anti-jammer radar capable of overcoming channel noise. The method is provided with a MIMO radar and at least one base station. The MIMO radar transmits the initial uplink signal and receives an ambient signal containing a reflected uplink signal and the downlink signal. The initial uplink signal is encrypted to overcome channel noise and jamming signals. The downlink signal is used to establish wireless communication between the base station and the MIMO radar. As such, the downlink signal is filtered and processed from the ambient signal. Similarly, the reflected downlink signal is also filtered from the ambient signal. Finally, the MIMO radar decrypts the reflected uplink signal to detect a plurality of targets and derive spatial positioning data for each target.

The reflected scanning beam is used to detect at least one low-resolution target. Subsequently, the MIMO radar transmits a plurality of initial tracking beams, wherein each initial tracking beams is directed towards a low-resolution target. This results in generation of a corresponding reflected tracking beam for each of the plurality of initial tracking beams. Finally, the MIMO radar detects at least one high-resolution target within each reflected tracking beam.

  • Patent number: 10794989
    Abstract: A method for target location approximation using orthogonal frequency-division multiplexing (OFDM) is provided with an OFDM device that consists of a wireless terminal and a multiple-input and multiple-output (MIMO) antenna. In order to derive a location approximation, a pilot uplink signal is transmitted through the wireless terminal towards at least one intended target. The pilot uplink signal that is transmitted is encoded as a direct-sequence spread spectrum (DSSS). Next, a reflected-pilot uplink signal is identified from an ambient signal that returns after the initial transmission. The reflected-pilot uplink signal is decoded to retrieve the original data embedded in the pilot uplink signal. A matching time delay is calculated between the pilot uplink signal and the reflected-pilot uplink signal. A direction of arrival (DOA) is determined from the MIMO antenna. Finally, the matching time delay and the DOA are used for location approximation.
