Echos still received at 300000 km

The quest to analyze and understand the data continues. I've done one full analysis pass over the whole low sample rate data and we get echos almost all of the time. We have short gaps in data when we cannot observe the echos due to transmitter pulses blocking our receiver (We transmit 2 ms of coded pulse every 16 ms).

Last measurement of the campaign at Feb 16th at 8 UT, when the rock was already 300000 km away from us! We could have still continued as we were still getting a signal. 

To start validating our analysis routines, I've sent a few range and Doppler measurements to NASA. Let's see how well our results fit.
