Measured Position at Nth Scan Solution

STEP 0: Pre-Calculation Summary

Formula Used

Measured Position at Nth Scan = ((Smoothed Position-Target Predicted Position)/Position Smoothing Parameter)+Target Predicted Position
x_n = ((X_in-x_pn)/α)+x_pn
This formula uses 4 Variables

Variables Used

Measured Position at Nth Scan - (Measured in Meter) - Measured position at Nth scan is the measured or actual position of target at the nth scan by the track-while-scan surveillance radar.
Smoothed Position - (Measured in Meter) - Smoothed Position is defined as the estimated present position of target by track-while-scan surveillance radar.
Target Predicted Position - (Measured in Meter) - Target Predicted Position is the predicted or estimated position of target at the nth scan by the track-while-scan surveillance radar.
Position Smoothing Parameter - Position Smoothing Parameter is the tuning parameter which is used to improve the quality of smoothed position estimated by the track-while-scan surveillance radar to avoid noisy measurements.

STEP 1: Convert Input(s) to Base Unit

Smoothed Position: 40 Meter --> 40 Meter No Conversion Required
Target Predicted Position: 74 Meter --> 74 Meter No Conversion Required
Position Smoothing Parameter: 0.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

x_n = ((X_in-x_pn)/α)+x_pn --> ((40-74)/0.5)+74

Evaluating ... ...

x_n = 6

STEP 3: Convert Result to Output's Unit

6 Meter --> No Conversion Required

FINAL ANSWER

6 Meter <-- Measured Position at Nth Scan

How do you choose a smoothing parameter?

When choosing smoothing parameters in exponential smoothing, the choice can be made by either minimizing the sum of squared one-step-ahead forecast errors or minimizing the sum of the absolute one- step-ahead forecast errors. In this article, the resulting forecast accuracy is used to compare these two options.
