the element in radarObjects mean in Forward Collision Warning Using Sensor Fusion

Forward Collision Warning Using Sensor Fusion using radar detections and its structure likes

% # |radarObjects|, a struct array with fields: timeStamp (see below),

% numObjects (integer) and object (struct). Each element of the array

% corresponds to a different timestep.

% |object| is a struct array, where each element is a separate object,

% with the fields: id, status, position(x;y;z), velocity(vx,vy,vz),

% amplitude, and rangeMode.

% Note: z is always constant and vz=0.

But how I create a radarObjects from real radar sensor. I don't know the meaning of id, status, amplitude and rangeMode. Thanks in advance.

The radarObject output is a detection, therefore it contains the information from the detected signal. If you have data from the real data sensor, you will have to perform signal processing techniques to arrive at those information. You may want to take a look at the following example showcasing how to simulate and process the raw radar signal
