Byte

Type

Description

0

char[4]

Identifier for a radar descriptor block (ascii characters "RADD").

4

long

Length of a radar descriptor block in bytes.

8

char [8]

Eight character radar name.

16

float

Radar/lidar constant

20

float

Typical peak power of the sensor in kw. Pulse energy is really the peak_power * pulse_width

24

float

Typical noise power of the sensor in dBm.

28

float

Gain of the receiver in db.

32

float

Gain of the antenna in db.

36

float

System Gain in db. (Ant G - WG loss)

40

float

Horizontal beam width in degrees. Beam divergence in milliradians is equivalent to beamwidth

44

float

Vertical beam width in degrees.

48

short

Radar Type (0)Ground, 1)Airborne Fore, 2)Airborne Aft, 3)airborne Tail, 4)Airborne Lower Fuselage, 5)Shipborne.

50

short

Scan Mode (0)Calibration, 1)PPI (constant Elevation) 2)Coplane, 3)RHI (Constant Azimuth), 4) Vertical Pointing, 5)Target (Stationary), 6)Manual, 7)Idle (Out of Control).

52

float

Requested rotational velocity of the antenna in degrees/sec.

56

float

Scan mode specific parameter #0 (Has different meaning for different scan modes).

60

float

Scan mode specific parameter #1.

64

short

Total number of parameter descriptor blocks for this radar.

66

short

Total number of additional descriptor block for this radar.

68

short

Data compression. 0 = none, 1 = HRD scheme.

70

short

Data Reduction algorithm: 1 = none, 2 = between 2 angles, 3 = Between concentric circles, 4 = Above/below certain altitudes.

72

float

1 = smallest positive angle in degrees, 2 = inner circle diameter, km, 4 = minimum altitude, km.

76

float

1 = largest positve angle, degress, 2 = outer cicle diameter, km, 4 = maximum altitude, km.

80

float
