A Double Sideband Linear Frequency Modulation System for Radar Applications.

reportActive / Technical Report | Accession Number: ADD008688 | Need Help?

Abstract:

A double sideband linear frequency modulation technique for radar applications is disclosed for obtaining simultaneous range and doppler measurements. The method of obtaining measurements is useful in a variety of radar applications however, the most promising area is in continuous wave radar systems. Linear Frequency Modulated LFM waveforms of both increasing and decreasing frequency are simultaneously transmitted. Upon reception these sideband signals are combined coherently to give an output that is a function of the targets radial velocity. The received signals are also processed separately to obtain target ranging information. Author
