Doppler Radar Blind Speed PRF Calculator

Radar Signal Processing: Balance the radar dilemma between maximum unambiguous range ($R_{ua}$) and first blind velocity ($v_{b1}$).

Pulse Repetition Frequency $PRF_1$ (Hz):

Carrier Frequency $f_0$ (GHz):

Target Radial Velocity $v_r$ (m/s):

Staggered PRF Ratio ($p / q$):

Pulse Width $\tau$ ($\mu\text{s}$):

Unambiguous Range

-- km

1st Blind Speed

-- m/s

Target Doppler ($f_d$)

-- Hz

Extended Blind Speed

-- m/s

• Radar Carrier Wavelength ($\lambda$): -- cm

• Pulse Repetition Interval ($PRI = 1/PRF$): -- $\mu\text{s}$

• Radar Dilemma Invariant ($R_{ua} \cdot v_{b1}$): -- $\text{km}\cdot\text{m/s}$

• 1st Blind Speed in Other Units: -- km/h (-- knots)
