Effects of Single-tone Spurious Responses on Signals in ESM Receivers

This article presents the effects of spurious responses in ESM receivers used to geo-locate threat emitters. These spurs contaminate the measured values of phase and frequency of detected signals in the receivers, beyond the effect of receiver noise, c...

Electronic Support Measures (ESM) receivers geo-locate threat emitters by measurement of angle of arrival (AOA), time difference of arrival (TDOA) or frequency difference of arrival (FDOA). Errors in the measurement of phase and frequency may be contaminated, due to spurious responses that yield irresolvable errors. Phase Contamination Radar signals...
