How cricket ball speed test tool Works

The Doppler Effect

When a radar gun emits radio waves at a specific frequency, the ball's movement changes the frequency of the reflected waves:

• As the ball approaches, waves are compressed (higher frequency)
• As the ball moves away, waves are stretched (lower frequency)

Speed Calculation

The speed is calculated using the Doppler shift formula:

Where:

• v = ball speed (m/s)
• Δf = frequency shift (Hz)
• c = speed of light (~3×10⁸ m/s)
• f₀ = emitted frequency (24.125 GHz)
• θ = angle between ball movement and radar (0° in our case)

Simplified Calculation

For cricket radar guns (θ ≈ 0°):

Example: A 1000 Hz shift ≈ 44.7 km/h

Radar Technology

Professional radar guns:

• Use K-band (24 GHz) or Ka-band (34 GHz) radar
• Measure speed within ±1% accuracy
• Can track speeds from 30-200 km/h

How It Works

Video Analysis Method

Our advanced algorithm analyzes video footage to calculate bowling speed:

1. Record your delivery from the side (about 10-15 meters from the pitch)
2. Upload the video to our system
3. Mark reference points (crease to crease distance)
4. Our system tracks the ball and calculates speed

Real-time Radar Method

When using professional equipment:

1. Set up the radar gun behind the bowler or at the pitch
2. Bowl normally toward the target
3. The radar measures speed as the ball passes
4. Instant results displayed on screen
