Tracking and Kalman filtering made easy P1
WHY TRACKING AND PREDICTION ARE NEEDED IN A RADAR Let us first start by indicating why tracking and prediction are needed in a radar. Assume a fan-beam surveillance radar such as shown in Figure 1.1-1. For such a radar the fan beam rotates continually through 360 , typically with a period of 10 sec. Such a radar provides two-dimensional information about a target. The first dimension is the target range (i.e., the time it takes for a transmitted pulse to go from the transmitter to the target and back); the second dimension is the azimuth of the target,...
