ADC spurious signal mitigation in radar by modifying the LO

Analog-to-digital converters (ADCs) used in MTI or pulse Doppler radars generate spurious signals from large clutter echoes because of the non-linear ADCs. These spurious signals can appear as real moving targets in the Doppler passband of a radar. The paper shows mathematically how these spurious signals are mitigated and a means of implementing the process is provided.
