Moving target identification without special radar mode

A method of determining velocity, the method comprising:

• receiving a radar return signal from a target, wherein the radar return signal comprises a first frequency ramp;
• determining an interval from a start of the first frequency ramp of the radar return signal, wherein a portion the radar return signal corresponding to the interval includes portions of the radar return signal other than the first frequency ramp;
• determining a plurality of usable samples for the first frequency ramp, wherein the plurality of usable samples exclude samples of the radar return signal corresponding to the interval;
• determining a subset of the plurality of usable samples, within the first frequency ramp;
• determining one or more frequencies present in the subset of the plurality of usable samples;
• and
• determining a Doppler velocity of the target based at least in part on the one or more frequencies present in the subset of the plurality of usable samples, within the first frequency ramp.

A radar system comprising:

• means for receiving a radar return signal from a target, wherein the radar return signal comprises a first frequency ramp;
• means for determining an interval, from a start of the first frequency ramp of the radar return signal, wherein the portion of the radar return signal corresponding to the interval includes portions of the radar return signal other than the first frequency ramp;
• means for determining a plurality of usable samples for the first frequency ramp, wherein the plurality of usable samples exclude samples of the radar return signal corresponding to the interval;
• means for determining a subset of the plurality of usable samples, within the first frequency ramp;
• means for determining one or more frequencies present in the subset of the plurality of usable samples;
• means for determining a Doppler velocity of the target based at least in part on the one or more frequencies present in the subset of the plurality of usable samples, within the first frequency ramp.
