Sensor coil optimization

1. A method of providing an optimized position locating sensor coil design, comprising:

receiving a coil design, the coil design including geometric positions of a transmit coil and geometric positions of receive coils;

linearizing one or more of the receive coils, wherein linearizing the receive coils includes

simulating a function of one of the receive coils as a function of target position,

determining a difference between the function and an ideal function of the one of the receive coils,

converting the difference to a geometric variation, and

applying a geometric variation to the geometric position of the receive coil; and

offset compensating the one or more of the receive coils, wherein offset compensating the receive coils includes

determining a simulated offset by simulating an output of one of the receive coils in the absence of a target;

determining an offset adjustment based on the output; and

adjusting the one of the receive coils according to the offset adjustment.

2. The method of claim 1 , wherein the receive coils include a sine receive coil and a cosine receive coil.

3. The method of claim 1 , wherein the function is a sine function.

4. The method of claim 1 , wherein the function is a cosine function.

5. The method of claim 1 , wherein the geometric variation is an array given by a geometric variation over the receive coil.

6. The method of claim 1 , wherein the offset adjustment is a constant shift over the one of the receive coils.

7. The method of claim 1 , wherein the offset adjustment includes finding an offset of the difference.
