Abstract: It is common practice in modern radar to utilize some type of downconversion to an intermediate frequency or baseband before analog-to-digital conversion takes place. Several microwave components are needed for this downconversion process, including a tunable local oscillator, bandpass filters, amplifiers, and other signal conditioning devices.

The manipulation of the received signals that was formerly done with microwave hardware is now done in a digital signal processor. In addition to simplifying the receiver hardware, this invention will also lead to better utilization of the frequency band, less interference from adjacent bands, improvements in system reliability and stability, reduction in system operation and maintenance costs, and will facilitate future system modifications and upgrades.
