Implementation of Moving target Indicator

can i implement mti on range doppler map by zeroing the velocity axis near zero?

[Jalal Khan]

it is range doppler map

Yes, you've already said that. Did you try my suggestions?

Not sure what that means. Explain "zeroing the velocity axis near zero".

You can certainly plot a symbol at a certain (x,y) point like this:

hPlot = plot(x, y, 'r+', 'LineWidth', 2, 'MarkerSize', 30);

and then to remove it in preparation for plotting the next point:

delete(hPlot);

[Jalal Khan]

in the array of data that contains velocity components in rows by making the values of that particular row (the values that contain the velocity compnents near zero) to zero as shown in image

[Image Analyst]

I still don't understand. How many components are there? There would be 3 if the object is moving in 3 dimensions, and 2 if it's moving in 2-D and 1 if it's moving along a line. You seem to have hundreds of velocity components. Why? If your object moving in a hundred dimensional space?

If you want to zero out a row in a matrix, do this

velocity(rowNumber, :) = 0;

If you want to zero out a column in a matrix, do this

velocity(:, columnNumber) = 0;
