The high-duty pulse-Doppler and CW signals in an electronic warfare environment usually determine the requirements on the processing throughput rate of the preprocessor in an EW receiver. To reduce the throughput, a subsystem that can remove adaptively the high-duty signals and measure their spectral signatures for tracking is highly desirable. A Doppler-parameter measurement system consists of an adaptive processing module (APM), a digital spectrum-enhancement module (DSEM), and a host interface module (HIM). The APM has been fabricated using in-house microwave integrated circuit technology; its primary function is to implement an adaptive least-mean-square filter. The DSEM and HIM modules are breadboarded using a programmable DSP chip. The function of the DSEM is to perform spectrum processing for enhanced spectral resolution to achieve specified tracking accuracy, whereas that of the HIM is to provide user interface to the DSEM and for spectrum display purposes.
