PULSE CHARACTERISTICS - created from Mind Map

Wavelength

Amplitude

Frequency

Pulse length

Pulse Repetition Frequency (PRF

directly related to beamwidth

short wavelength = narrow beam

Directly related to power

High waves = more power

Wavelength and frequency are related

decrease wavelength = frequency increase

Frequency = c/wavelength

measured from leading edge to back

Pulse length = power

Pulse length - range resolution

Ideal to have short powerful pulses

Max Unambiguous range

Listening Time

Antenna Motion

Dwell Time

Range Folding (Second-Trip Echoes)

greater PRF = shorter unambiguous range

Rmax = c/2PRF

The wait between pulses

determined by PRF

Revolution per min

increase PRF if rotation is faster

Dwell = target presentation

PRF = Dwell time

1/2 distance traveled

Azimuth is good, but range is wrong

Typical elongated
