ESTIMATED RTE POWER CONSUMPTION

 

X Band Current

SX both S & X Band Current

Standby

0.4Ah / 0.6W/h

0.6Ah / 0.9W/h

1 Radar

0.5Ah / 0.74W/h

1.2Ah / 1.8W/h

10 Radar at same time
(assume 3 close range)

1.5Ah / 2.5W/h

3.2Ah / 4.8W/h

 

   


The following calculations were used and make an assumption of radar parameters as follows.
X Band PRI 1KHz, Pulse width 1uS antenna Beam width 3 degrees, antenna rotation 25rpm.
S Band PRI 700Hz, Pulse width 2uS Antenna Beam width 5 degrees, antenna rotation 25rpm.
In standby without any radar interrogations the RTE will take the following current from the battery

 

X Band Current

SX both S & X Band Current

Standby

8mA

12mA

1 Radar

10.25mA

24.5mA

10 Radar at same time
(assume 3 close range)

30.6mA

65.7mA

 

 

 

This would equate to a daily use of the following

 

X Band Current

S & X Band Current

Standby

192mAh

290mAh

1 Radar

246mAh

588mAh

10 Radar at same time
(Assume 3 close range)
