The first answer is incorrect.
Radar measures how far away something is by the time delay between the transmitted pulse and the reflected pulse returning. Power indicates the size (electrical size not physical size) of the thing that is reflecting the power (aircraft for instance). While the power IS also a function of range (the power falls off as the signal goes out and back (by R^2 each way) that measure of size does not in itself give range as noted above. If you knew the cross section (electrical size) you could conceivably measure power and compute range but cross section fluctuates several orders of magnitude based on aspect ratio so its probably unrealistic.
The comment that doppler shift is used to determine distance is also wrong. Doppler shift gives velocity information and no range.
Jamming can be denial (hiding the aircraft) or deceptive (confusing the radar with more attractive things). This can be playing back recorded data or just using a modulated noise source.
This page has a good list of jamming types:
