Abstract
In passive radar based on illuminators of opportunity, one of the key problems is the suppression of the direct path interference (DPI) from the illuminator. This paper analyzes the DPI and the effect of which on passive radar in practical application, and demonstrates the importance of the suppression of DPI prior to analog to digital converter (ADC). Based on which, a new, efficient, automatic cancellation solution via hardware is brought forward. Real experiments indicate over 30 dB of the DPI suppression can be obtained
