摘要： An improved obstacle detection radar system and method of operation in which the detection sensitivity is normalized with respect to target range without significantly increasing system complexity or cost, while at same time improving the system response time. The system consecutively integrates the received radar illumination corresponding to each of several contiguous range bins over different dwell intervals specific to the respective range bins. In particular, the dwell intervals are progressively reduced for the range bins nearest the system antennas, thereby reducing the detection sensitivity in those range bins, and at the same time, reducing the time required to completely scan all of the range bins. As a result, the signal attributable to the side-lobe patterns is inherently attenuated, the sensitivity is more normalized, and system response time is improved. Accordingly, the probability of detection for a given target within the desired detection range is less dependent on its distance from the radar system.
摘要翻译：改进的障碍物检测雷达系统和操作方法，其中检测灵敏度相对于目标范围进行归一化，而不显着增加系统复杂性或成本，同时改善系统响应时间。该系统在对应于各个范围仓的不同驻留间隔上连续地对应于几个连续范围箱中的每一个对应的接收到的雷达照明。特别地，对于距离系统天线最近的范围仓，停留间隔逐渐减小，从而降低了这些范围仓中的检测灵敏度，同时减少了完全扫描所有范围仓所需的时间。结果，归因于旁瓣图案的信号固有地衰减，灵敏度更加规范化，并且系统响应时间得到改善。因此，在期望的检测范围内给定目标的检测概率较少取决于其与雷达系统的距离。

摘要： Systems and methods that use a CW Doppler radar to monitor paint particle velocities as they are sprayed from a paint gun to optimize the application of sprayed paint onto the object, and provide a closed loop spray painting system and paint spraying method that controls the application of paint in real time using data generated by the radar. The Doppler radar and a signal analyzer are used to analyze the Doppler return signals and display data indicative of the velocity of the paint particles. The data may be used by an operator to manually adjust the paint spray system. In addition, the spectrum analyzer may be used to generate and couple control signals to the paint spray system to provide for closed loop feedback control of thereof. One method comprises the following steps. Spraying paint particles toward an object that is to be painted using a paint spray gun. Radiating Doppler radar signals at the paint particles that are moving toward the object. Receiving backscattered Doppler shifted radar returns from the moving paint particles. Processing the received backscattered Doppler shifted radar returns to produce data indicative of the velocity of the paint particles. Displaying the data indicative of the velocity of the paint particles. This method unobtrusively and remotely measures paint particle velocity and velocity distribution. By additionally generating control signals in response to the data, the paint spray system is controlled.
