Abstract
A wideband pulsed energy system having improved signal-to-clutter response, and utilizing a chirped or frequency-modulated carrier pulse having a preselectively amplitude modulated envelope. A non-linear receiver-mixer cooperates with a successive intermediate frequency stage (the bandwidth of which correponds to the amplitude modulation bandwidth) for providing an output corresponding to the modulation envelope.
Claims8
In a pulse-type energy system,
- Means for transmitting a linearly frequency-modulated carrier wave pulse having a preselected one of a fixed frequency and chirped amplitude modulation envelope;
- and
- Receiving means responsive to received echoes of said transmitted pulse for providing an output corresponding to said modulation envelope.
