RSP1 Radar Processor

Datasheet

3 Sensor Configurations

RSP1 Chip may be used with one or two sensors. Sensors can not be used in parallel, but as alternative

sensor connected to the Alt_RADAR inputs. Inputs can be selected by parameter S01.

Channels

Sensor examples

Comments

1 ("mono")

K-LC1a, K-LC3

Lowest cost. Mostly used for indoor applications

2 ("stereo")

K-LC2, K-LC5, K-LC6, K-MC1

Directional detection, excellent interference suppression

Table 1: Sensor Configurations

3.1 Single channel vs Dual channel (I/Q) processing

RSP1 can be operated with dual channel ("stereo") I/Q sensors as well as with one channel ("mono")

sensors (see Table 1: Sensor Configurations).
