Counter to find the delay between a radar and an object

Good evening, I am doing a project to measure a distance between a Radar and an object. I am sending a pulse throw the FPGA (DE0-nano) to the radar and I am receiving the signal echo in the FPG...

ADC on DE0-nano has a maximum sampling rate of 200 kS/s, so it's not suitable to measure radar time-of-flight.

For a digital input signal, a resolution in a 1.5 ns range is feasible with a single clock and double data rate technique. Higher resolution optionally with phase shifted clocks.
