You should compute the Cumulative Gain of this RF Chain (https://en.wikipedia.org/wiki/RF_chain) and use that to develop a Link Budget computation (https://en.wikipedia.org/wiki/Link_budget), and then show the result. Radars have a special formulation of Friis equation called the Radar Range Equation (https://en.wikipedia.org/wiki/Radar#Radar_range_equation). This result can be used to estimate the Received Power Levels at the antenna, which can then mapped to expected Voltages at the ADC. In doing so, you can effectively determine whether or not the "echo" off the golf ball will be "loud" enough for the receiver to "hear."
This is the first step in debugging a system like this: setting an expectation and observing whether it is met. If the radar link budget does not close, you can specify a low noise amplifier to plug in to the receive path to boost signal gain. If the link budget does close, you can progress the debugging to further along in the digital processing chain.
