Blind speeds—
Clutter rej. (dB)—
Improvement (dB)—
MTI Canceller
y[m] = x[m] - x[m-1] (single)
Highpass in slow-time → rejects clutter (zero Doppler)

Blind speeds:
vblind = nλPRF/2
Target at blind speed → zero response!

Pulse Doppler (FFT):
FFT across pulses → Doppler filter bank.
Much better clutter rejection + velocity measurement.
