Could the Joshan pesa be added to Bavar to make it passive, if the need should arise?
Can a system have both an aesa and pesa and switch between them?
Yes. Theoretically yes. I am not sure if it is practically done but it can be added to AESA radars to be used in specific situations.
PESA is not passive radar...it is named pesa because it use one transmitter for all arrays ,unlike AESA...where all modules are also transmitters and recivers but PESA is radar which transmit and recive signals as any radar...
It is just a military jargon. Not really passive.
The separate pure receiver component will be passive which is a plus.
