Abstract
Cooperation and competition of solid state and vacuum microwave devices in radar applications
Highlights
Important radar’s parameter is velocity of beam control, which influences a number of simultaneously handled targets
Besides this very remarkable feature of active electrical scanned array (AESA) is the absence of frequency and directional selectivity of each single module
This means that the circuit of each module receives all interference signals from hemisphere. This implies requirement of very large linearity and dynamic range of the receiver (~120 dB) which is not so easy to realize. This means that AESA possesses increased vulnerability to countermeasures and interferences
Summary
Important radar’s parameter is velocity of beam control, which influences a number of simultaneously handled targets. Besides this very remarkable feature of AESA is the absence of frequency and directional selectivity of each single module. This means that the circuit of each module receives all interference signals from hemisphere.
