Earlier I wrote a thread on new AESA radar and gave caution to JF-17 to be very careful before going for AESA absolutely. ASES radar will reduce the price tag of JF-17 from present 30 miliion $ to 10 million $ . Because AESA radar TEC is very cheap and more durable.
I thought it would be better to contrast and compare the tubes vs. solid-state debate for new AESA radar.
I'd readily concede that solid-state/transistor components are, watt for watt, cheaper, more reliable, cooler running, smaller and lighter in weight. But if solid-state is so terrific why haven't tubes become extinct in the half century since transistors came onto the scene?
AESA Radar is based on pure solid state therefore they are very very cheap compare to present Mechanical JF-17 Radars.
ASEA radar have many properties those including, easy to construct , easy to cool down and very light in weight! But these same can be ACHIEVED FOR MECHANICAL RADAR TOO HOWEVER IT WILL COST MORE EFFORT AND MAY MONEY TOO. THEREFORE WEST R SWITCHING FOR AESA RADARS TO REDUCE COST
Here I used some video examples for folk irrespective if have science background or not to demonstrate my point that present mechanical radar is superior than to AESA!!
Watch out videos and used analogy to conclude if AESA or Mechanical Radar!
Agile Beams: Active Electronically Scanned Array Radars
AESAs aim their "beam" by broadcasting radio energy that interfere constructively at certain angles in front of the antenna. They improve on the older passive electronically scanned radars by spreading their broadcasts out across a band of frequencies, which makes it very difficult to detect over background noise. AESAs allow ships and aircraft to broadcast powerful radar signals while still remaining stealthy. Above is AESA on F22
The AN/APG-80 system is described as "agile beam", and can perform air-to-air, search-and-track, air-to-ground targeting and aircraft terrain-following functions simultaneously and for multiple targets. As a SAR system utilizing NG's fourth-generation transmitter/receiver technologies, it has a higher reliability and twice the range of older, mechanically-scanned AN/APG-68 radar systems. Above is F-16 APG-80 Radar
Now read that report too!! Report of the Defense Science Board Task Force on FUTURE DoD AIRBORNE HIGH-FREQUENCY RADAR NEEDS/RESOURCES
