Radar Report Data

Host MCU can receive one of three kinds of report data types through the serial port from XenD101MM.

Users can repeatedly receive different types of data depending on the working mode.

 

 

 

 

 

1. Report Data in Normal Working Mode

In the normal working mode, XenD101MM outputs the detection results via the serial port.

The output data are ON/OFF strings as well as the range gate of the detected target.

 

Setting Working Mode

Command	Description
FD FC FB FA 04 00 FF 00 01 00 04 03 02 01	Enter to Config Mode
FD FC FB FA 08 00 12 00 00 00 64 00 00 00 04 03 02 01	Normal working mode = 0x0064
FD FC FB FA 02 00 FE 00 04 03 02 01	Leave Config Mode

 

 

Report Format

Header	Data	Tailer
4F 4E 0D 0A	String Message of ” ON/OFF, Range N”, N is range gate number	0D 0A

 

 

RX Data via Serial Port

Display in UTF-8 string

 

 

 

 

 

2. Report Data in Debugging Mode

The RDMAP data of all the range gates of a certain chirp are sent out each time,

i.e., the data of all the 16 range gates of the first chirp will be sent out first, then goes the second chirp, and so on.

 

Setting Working Mode

Command	Description
FD FC FB FA 04 00 FF 00 01 00 04 03 02 01	Enter to Config Mode
FD FC FB FA 08 00 12 00 00 00 00 00 00 00 04 03 02 01	Report in debugging mode(0x0000)
FD FC FB FA 02 00 FE 00 04 03 02 01	Leave Config Mode

Header	Data	Tailer
AA BF 10 14	RDMAP: 20(Doppler) * 16 (number of range gate) * 4(square of the amplitude)	FD FC FB FA

  3. Report Data in Reporting Mode

 

Setting Working Mode

Command	Description
FD FC FB FA 04 00 FF 00 01 00 04 03 02 01	Enter to Config Mode
FD FC FB FA 08 00 12 00 00 00 04 00 00 00 04 03 02 01	Report in reporting mode(0x0004)
FD FC FB FA 02 00 FE 00 04 03 02 01	Leave Config Mode

 

 

Report Format

Header	Data Length	Data			Tailer
		Detection Result	Target Distance	Range Gate Energy
F4 F3 F2 F1	2 bytes	1 Byte ♦ 0x00(no target) ♦ 0x01(target exist)	2 Bytes	32 Bytes (16 * 2 bytes)	F8 F7 F6 F5

 

 

RX Data via Serial Port (Data is re-arranged after RX)

 

 

The first range gate is biggest energy(0x1BF2), So made a decision that object is there.

Length of the data	The sum of data length of Detection Result, Target Distance, and Energy of Each Range Gate. ex) 00 23 → 35 Byte(Detection Result + Target Distance + Energy of Each Range Gate)
Detection result	Whether a target is detected ex) 01 → a human target is detected in current scenario
Target distance	The radial distance between the detected target and the radar. ex) 0069 →  The radial distance between the detected target and the radar = 105 cm
Energy of range gate	The energy value of each range gate (0~15) ex) Range gate 0 = 1BF2,  Range gate 1= 076A,  Range gate 2 = 0014, Range gate 3 = 0028, etc…..,
