Question: I can vary the amount of nanoseconds in GAS. How does that affects the depth and resolution?
Short answer: It doesn't affect the penetration depth at all, but only how long range you can see. It affects the resolution directly.
Long answer: The penetration depth is a function of the properties of the media one is surveying, not the settings in your radar system. Using longer time range than necessary will not improve the penetration depth, but will reduce the SNR of your collected data. The resolution of CobraLocator is related directly to the time range as with any sampling system using a fixed amount of samples/trace. Increasing the range will reduce the resolution.

Not necessarily, if the resolution is fixed increasing the range increases the amount of samples.

In this particular case that's not the situation because the amount of samples is fixed to 512 for all ranges.
