1. A collision avoidance system, adapted to a carrier and comprising:
a radar;
an output device; and
a processor, coupled to the radar and the output device and configured to:
detect a first detection area and a second detection area through the radar to generate a detection result of a target object, wherein the second detection area comprises the first detection area and is larger than the first detection area;
determine whether the target object invades the first detection area or the second detection area based on the detection result;
in response to determining that the target object invades the second detection area but does not invade the first detection area, calculate a first collision probability based on a first weight and the detection result;
in response to determining that the target object invades the first detection area, calculate the first collision probability based on a second weight and the detection result;
determine whether to output an alarm message based on the first collision probability; and
in response to determining to output the alarm message, output the alarm message through the output device.
