Radar scanner

Sam is driving a stealth helicopter with maximum speed $\pi\text{ km/sec}$ . His aim is to invade an army base, i.e reach it without getting detected by the radar scanner. He knows that the radar scanner (of the base) has a maximum range of $1300\text{ km}$ , and is in the form of a line (like shown in the picture) which rotates at a rate of 1 degree per second.

Can he make it?

Note: by stealth, I mean that the radar scanner is the only way for the enemy to detect his helicopter.
