In this paper, we propose a simplified algorithm for the unbiased estimation of range and the radial velocity of moving objects observed by a sensor with a frequency-modulated continuous wave signal. Linear frequency modulated signals and their different modifications are widely used in various microwave sensors for short- to medium-range measurements in automotive, safety, industrial, and other applications...
We present a performance evaluation of the inexpensive security or surveillance system. The system consists of a radar network that creates a virtual fence or invisible barrier. The main focus of this paper is on testing a prototype of the radar network node hardware and software in a cluttered indoor environment. The radar network node operation is a combination of remote sensing by commercially...
We present a novel approach which is helpful in building an inexpensive security or surveillance system for various applications. The system consists of a radar network that creates a virtual fence or barrier that is invisible, and in case of intrusion it will give an alarm, determine the location of a target and provide the target's relative velocity information. Our approach is a combination of...
