Distance Value Target: Select the distance chirp_data.distance[0] from the point of maximum signal strength obtained in demo_findTopTanges

Range: Chirp Budget Calc_09_25_18 of sprcah9.

Question: the customer would like to know why the error is so large

1. Range With DEMO_CONFIG 30: the actual test will basically not measure the distance value at more than 20 meters.

2.Range With DEMO_CONFIG 75: the actual measurement can measure 70 meters, but the error is about 1 meter at 50 meters, about 1.5 meters at 60 meters, and over 2 meters at 70 meters.
