A METHOD OF SEPARATING APPROACH AND RECEDE PULSE DOPPLER RADAR ECHOES
A doppler-sense separation technique, applicable to the Madre radar system, separates radar targets into approaching and receding targets. The presentation of unambiguous doppler frequencies of up to one-half the radar sampling rate is made possible. In addition, three desirable collateral features...

Zusammenfassung: | A doppler-sense separation technique, applicable to the Madre radar system, separates radar targets into approaching and receding targets. The presentation of unambiguous doppler frequencies of up to one-half the radar sampling rate is made possible. In addition, three desirable collateral features can be obtained: (a) some suppression of earth backscatter returns, (b) simple i-f bandwidth control, and (c) the availability of range-gated and essentially continuous-wave signals. The separation technique has a theoretical signal-to-noise ratio improvement of 3 db. |
