WebModern systems dynamically measure clutter 2.2 FTC (Fast Time Constant) levels for a large numeral of cells within the coverage area of the radar. These measurements are slowly adjusted to take The shorter … WebAbstract: Constant false alarm rate (CFAR) detection has been widely used in through-the-wall radar. However, there is a low probability of detection for transverse motion when using the CFAR detection in the slow time dimension; while it is easy to misjudge fixed targets with strong reflection to moving targets when CFAR detection used in the fast time …
