## Measured position at the nth scan Solution

STEP 0: Pre-Calculation Summary
Formula Used
measured_position_at_nth_scan = ((Smoothed position-predicted position of the target)/position smoothing parameter)-predicted position of the target
xn = ((xin-xpm)/α)-xpm
This formula uses 3 Variables
Variables Used
Smoothed position - Smoothed position is the estimation of target present position (Measured in Meter)
predicted position of the target - predicted position of the target (Measured in Meter)
position smoothing parameter- position smoothing parameter is smoothing parameter
STEP 1: Convert Input(s) to Base Unit
Smoothed position: 4 Meter --> 4 Meter No Conversion Required
predicted position of the target: 1 Meter --> 1 Meter No Conversion Required
position smoothing parameter: 9 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
xn = ((xin-xpm)/α)-xpm --> ((4-1)/9)-1
Evaluating ... ...
xn = -0.666666666666667
STEP 3: Convert Result to Output's Unit
-0.666666666666667 --> No Conversion Required
FINAL ANSWER
-0.666666666666667 <-- measured position at the nth scan

### FAQ

What is Measured position at the nth scan?
The Measured position at the nth scan formula is defined as the last position or nth position scanned in a radar system and is represented as xn = ((xin-xpm)/α)-xpm or measured_position_at_nth_scan = ((Smoothed position-predicted position of the target)/position smoothing parameter)-predicted position of the target . Smoothed position is the estimation of target present position, predicted position of the target and position smoothing parameter is smoothing parameter.
How to calculate Measured position at the nth scan?
The Measured position at the nth scan formula is defined as the last position or nth position scanned in a radar system is calculated using measured_position_at_nth_scan = ((Smoothed position-predicted position of the target)/position smoothing parameter)-predicted position of the target . To calculate Measured position at the nth scan, you need Smoothed position (xin), predicted position of the target (xpm) and position smoothing parameter (α). With our tool, you need to enter the respective value for Smoothed position, predicted position of the target and position smoothing parameter and hit the calculate button.
