1. Sonar and lidar systems also have PRFs, as does any pulsed system . 2. Their pulsed system used a new Philips magnetron with better frequency stability. 3. Low-flow pulse systems can be left operating continuously without overwatering. 4. Different pulse systems are used, varying from country to country. 5. Pulsed systems are typically expensive and require extensive maintenance.6. Both continuous wave and pulsed systems are used. 7. The SFR pulsed system was set up near Paris where it detected aircraft at ranges up to. 8. Green Satin was a pulsed system , although it was not a pulse-doppler radar in the typical meaning. 9. Pulsed systems use signal timing to obtain vertical distance resolution, whereas continuous wave systems rely on detector focusing.10. However, there is still multipath propagation and inter-pulse interference to fast-pulse systems , which must be mitigated by coding techniques.
