    • According to one embodiment, a radar equipment includes a radio transmitter, a pulse compressor, a Doppler filter, and an integration processor. The radio transmitter receives pulse signals and digitizes the received pulse signals by oversampling with a frequency higher than that for generation of a pulse compression coefficient to generate digital data. The pulse compressor performs pulse compression on the digital data using the pulse compression coefficient to generate range bin data for each of the pulse signals. The Doppler filter processor performs Doppler filter processing on the range bin data. The integration processor integrates the range bin data subjected to the Doppler filter processing for each range bin.
    • 根据一个实施例,雷达设备包括无线电发射机,脉冲压缩器,多普勒滤波器和集成处理器。 无线电发射机接收脉冲信号并通过用比产生脉冲压缩系数的频率更高的频率进行过采样对接收的脉冲信号进行数字化,以产生数字数据。 脉冲压缩器使用脉冲压缩系数对数字数据执行脉冲压缩,以产生每个脉冲信号的范围bin数据。 多普勒滤波器处理器对范围仓数据执行多普勒滤波处理。 集成处理器集成了对于每个范围仓进行多普勒滤波处理的范围仓数据。

    • According to one embodiment, a radar device includes a radio module, a pulse compressor, a Doppler filter processor, a signal processor, an integration processor, an estimation module and a target detector. The radio module receives a plurality of received pulses corresponding to transmission pulses transmitted from a transmitter. The integration processor generates third data by integrating first data generated at the signal processor with second data generated based on first data obtained by a previous scan. The estimation module estimates a position at a time of a next scan based on the third data to generate second data. The target detector detects a target based on the third data.
    • 根据一个实施例,雷达装置包括无线电模块,脉冲压缩器,多普勒滤波处理器,信号处理器,集成处理器,估计模块和目标探测器。 无线电模块接收与从发射机发送的传输脉冲对应的多个接收脉冲。 集成处理器通过将在信号处理器处产生的第一数据与基于由先前扫描获得的第一数据生成的第二数据进行集成来生成第三数据。 估计模块基于第三数据估计在下次扫描时的位置以产生第二数据。 目标检测器基于第三数据检测目标。
