What you need is a detailed knowledge of radar system. Antenna is only one part of it.

Read Skolnik or another radar textbook. On the forum it makes no sense to write long explanations.

How about simply check on FCC / ETSI limitations for your product, and use nearly maximum allowed power. You can always attenuate. And, as it says somwhere on the net, "remember, gain is cheap!" =)
