If a radar pulse contains 300 cycles of RF energy at a frequency of 600 MHz, the physical length of the pulse is:
1550 metres
150 metres
1.5 metres
0.15 metres
Wavelength = c / frequency
c = 300 000 000 m/sec. f = 600 MHz = 600 000 000 cycles/sec
Wavelength = 300 000 000 / 600 000 000 = 0.5 metres
Pulse length =cycles x wavelength
Pulse length = 300 cycels x 0.5 m/cycle = 150 metres
