ABSTRACT:
A CFAR estimator-correlator comprises an estimating filter responsive to the signal-plus-noise input process for providing an estimate of the signal waveform. The estimate and the signal-plus-noise process are applied to a correlator. An amplitude limiter interposed between the signal-plus-noise input and the correlator and a bandpass amplitude limiter interposed between the estimating filter and the correlator impart a CFAR characteristic to the apparatus. An interferometer is configured by utilizing separate sensors to provide a signal-plus-noise input process and a further signal-plus-noise input process to the amplitude limiter coupled to the correlator and to the estimating filter, respectively.
