Radar Pulse Compression Ambiguity Calculator
Radar Waveform Engineering: Compute Linear Frequency Modulation (LFM) chirp pulse compression ratio, range resolution ($\Delta R$), and range-Doppler cross-coupling errors.
Chirp Waveform Parameters
Compression Gain & Resolution
Compressed Range Resolution ($\Delta R$)
-- m
Raw Uncompressed: -- m
Time-Bandwidth Product ($TBP$)
--
Compression Gain: -- dB
Range-Doppler Coupling Error
-- m
Target Doppler f_d: -- kHz
Compressed Pulse Width ($\tau_{\text{comp}}$)
-- ns
Chirp Rate: -- MHz/µs
Matched Filter Metrics:
• Peak-to-first-sidelobe ratio (PSLR): -- dB
• Blind zone distance ($R_{\text{blind}} = c\tau / 2$): -- km
• Doppler shift shifts the apparent target range by $\Delta R = -v_r (f_0 / \mu)$.
