b) After each surveillance update a new range measurement is available for each target. Since the measurement includes errors, it must be smoothed based on previous measurements to obtain improved estimates of the current target position and velocity. The range and range rate estimation equations are as follows: r(t) estimate = r(t) prediction + [alpha × (r(t) measurement – r(t) prediction)] r (t) estimate = r (t – Tp) estimate + [(beta/Tp) × (r(t) measurement – r(t) prediction)], where Tp is the time difference between the current and previous measurements.
