ABSTRACT:
An improved high frequency radiometric system features time shared passive and active modes of operation for correlation of active and passive signal returns. The processed, normalized, and stored passive signals are subtracted from similarly treated active signals to suppress the effect of returns from back ground terrain, thus enhancing true target recognition. A second channel provides discrimination against jamming and spurious signals, thus reducing false alarms.
