    摘要: A radar signal processing device is provided, which performs a scan correlation in a polar coordinate system to secure accuracy of the scan correlation, and prevents a suppression of a target object moving at high speed due to the scan correlation. A polar coordinate correlator performs, in a polar coordinate system, a correlation between reception data and previous correlated data stored in a previous data storage. A trend curve calculating module calculates a trend curve of a distance-direction signal level of the reception data in the polar coordinate system. A target detecting module detects a target based on the signal level of the reception data and the trend curve. Further, the polar coordinate correlator changes the contents of the correlation of the reception data based on the target detection result from the target detecting module.

    摘要: A method of detecting an object includes receiving first reflected radio frequency (RF) signals from a region using an antenna and generating a first backscattering signature of the region from the first reflected RF signals.

    摘要: A stepped-frequency radar signal is transmitted through a barrier. A transmitter of the stepped-frequency radar is on a first side of the barrier, a first object is on a second side of the barrier, and a second object that is distinct from the first object is on the second side of the barrier. A signal including a reflection of the transmitted signal from the first object and a reflection of the transmitted signal from the second object is sensed. The sensed signal is analyzed to determine that a first detection is associated with the first object and a second detection is associated with a second object.
