    摘要： The embodiments of the present application relate to the technical field of signal processing, and provided a radar signal processing method, a radio signal processing method, and a device. The radar signal processing method includes: after an echo signal is mixed based on a local oscillator signal, and digital signal processing is performed to obtain a signal to be processed, the signal to be processed is subtracted based on a datum difference frequency signal to obtain a target signal, and a travelling speed of a target relative to a radar and/or a distance of the target relative to the radar is determined according to the target signal. Since the datum differential frequency signal is a signal obtained by mixing a leakage signal based on the local oscillator signal and performing the digital signal processing in a target free environment, that is, the datum differential frequency signal can represent information of the leakage signal in the actual measurement process. Therefore, subtracting the signal to be processed based on the datum differential frequency signal can effectively reduce the content of the leakage signal in the signal to be processed, reduce an impact of the leakage signal on the measurement result, thereby improving the accuracy of the measurement results.

    摘要： Systems and methods for determining a presence of cargo within a container are described. The determination may comprise transmitting a first electromagnetic signal within the container and receiving a first reflected electromagnetic signal corresponding to the first electromagnetic signal. The first reflected electromagnetic signal may be converted into a set of first magnitude values corresponding to a set of bin values representing a respective distance from the radar device. The first magnitude values may be integrated, using a moving window, over successive subranges of bin values to produce a set of integrated magnitude values. A set of integrated base magnitude values may be subtracted from the set of integrated magnitude values to produce a set of normalized integrated magnitude values. A presence of cargo within the container may then be determined by comparing each of the normalized integrated magnitude values with corresponding threshold values.
