    • Methods, apparatus, and computer program products are provided for tracking at least one moving target with a radar device without requiring the use of Doppler information. The invention comprises scanning an area with radar signals at a first time to receive a first plurality of target data signals indicative of a position of the target at the first time and determining the position of the target at the first time by collecting the first plurality of target data signals into a first target data grouping, such that the first target data grouping defines a first reference point. Similarly, a second reference point for the target is determined for a second time, and the position of the first reference point is compared to the position of the second reference point to track the moving target. Advantageously, the tracked positions of the moving target may be used to predict a future position of the target at a subsequent time.

    • Methods, apparatus, and computer program products are provided for improving the crossrange resolution of a radar device for more accurate determinations of angular position of a target. The radar device transmits and receives scanning signals at crossrange beam positions having a beamwidth, wherein the beam positions are separated by a step. The radar device scans a target to receive target data from at least three beam positions, typically consecutive beam positions, to determine a first beam position with a first target data value that is greater than a second target data value of a second beam position preceding the first beam position and greater than a third target data value of a third beam position following the first beam position. A target data relationship between the first, second, and third beam positions is determined to provide the angular position of the target relative to the first beam position.
    • 提供了方法,装置和计算机程序产品,用于提高雷达装置的交叉分辨率,以更精确地确定目标的角位置。 雷达装置在具有波束宽度的十字架波束位置处发射和接收扫描信号,其中波束位置通过台阶分离。 雷达设备扫描目标以从至少三个波束位置(通常是连续波束位置)接收目标数据,以确定具有大于第二波束位置之前的第二目标数据值的第一目标数据值的第一波束位置 第一光束位置并且大于第一光束位置之后的第三光束位置的第三目标数据值。 确定第一,第二和第三光束位置之间的目标数据关系以提供目标相对于第一光束位置的角位置。
