Introduction to Chips+Salsa

Flat Earth Chips+Salsa is a suite of radar-based hardware modules with companion software that make it easy and flexible for our customers to develop and deploy sophisticated radar applications. Chips+Salsa development kits are an ideal development platform for customers seeking full control of the radar, access to raw radar data and the ability to develop their own radar applications.

Our Chips+Salsa concept is composed of a Flat Earth software suite (Salsa) and multiple radar modules (Chips), or capes. Chips+Salsa Development Kits are designed to reach most markets we serve today; health care, home automation, proximity sensing, robotics, climate sensors and general GPR applications.

Built on the BeagleBone Black platform, kits come with a radar cape, an antenna cape, and all accessories that will have you up and running radar demonstrations with in an hour of opening up your new kit!

Salsa Software

Salsa Software provides a real-time, web-served radar viewer, SalsaScope, as well as the Salsa Software Development Kit (SDK): containing a radar and DSP library, a MATLAB toolbox, a Python wrapper, and a host of scripts and demonstration applications (web-based and embedded). Application demonstrations include Ranging, Zone Sense, Doppler and Motion Detection, Respiration, Temperature, and Frame Rate. Supported environments include Python, MATLAB, Eclipse, C, C++ and Linux. SalsaWeb, the web-served interface, allows a user to display output on any platform supporting Chrome, Firefox, Safari, or IE 10.

Ancho

The Ancho development kit is based on the Novelda XeThru X2 system on chip (SoC) (4.5 – 9.5 GHz) radar technology. The Ancho is suitable for ranging, tracking, sensing and positioning applications that can be used in Building Automation, Health Care, Industrial Machine Control, and Proximity Sensing markets. The Ancho has several antenna options including sinuous, patch, and linear tapered slot styles.

Cayenne

The Cayenne development kit is based on the Novelda XeThru X1 (0.9 – 7.0 GHz) radar technology. The Cayenne is suitable for ranging, tracking, sensing and positioning applications where the environment can be demanding and penetration is essential. Cayenne applications include environmental monitoring, infrastructure monitoring, and ground penetrating radar.

Chipotle

The Chipotle development kit is based on the Novelda XeThru X1 (0.8 – 4.0 GHz) radar technology. This is a lower frequency configuration of the X1 chip. The Chipotle is suitable for ranging, tracking, sensing and positioning applications where the environment can be demanding and penetration is essential. Chipotle applications include environmental monitoring, snow science instrumentation, and ground penetrating radar.

Salsa Software Suite

SalsaWeb

Web-served radar viewer, SalsaScope, to render raw data and adjust radar parameters and custom filtering. Multiple Demos, hardware pin-out, software updater, and user documentation included.

SalsaLib

Extensive Digital Signal Processing (DSP) and radar-helper library for use in SalsaScope and embedded application development.

SalsaLab

MATLAB toolbox to interface Salsa Development Kits directly to MATLAB. A MATLAB wrapper, GUI-based Apps, and numerous examples are included.

SalsaPy

Python wrapper to interface Salsa Development Kits directly to the Python environment on a host PC.  Examples accompany the wrapper for a rapid start.

C Source

Embedded application demonstrations and their associated source code using the SalsaLib Application Programming Interface (API). Several sample applications build on one another to demonstrate how to assemble and create your own radar application.

 

 

Salsa Scope

SalsaScope is a radar viewing application that allows you to experiment with the radar hardware and the radar library that comes with your Chips+Salsa Dev. Kit. The center of the SalsaScope page is the radar signal viewer; this is where the radar signal generated by your Dev. Kit is displayed. The vertical scale can be displayed in raw DAC Counter values or Volts, while the horizontal scale can be displayed in Samplers or Meters. The left portion of the SalsaScope page is the interface to the radar library with samples of common filters and variables used in Chip+Salsa, e.g. Static cluttermap and MTI Filter. The lower-left portion controls the frame rate governor which can be set to precisely control the radar signal capture frame rate. The right portion of the SalsaScope page is the interface to access all radar chip register settings, automatically displayed for the appropriate hardware. SalsaScope also provides access to all the applicable radar Actions, e.g. MeasureAll for timing calibration. The A-Scan is the original or typical radar display that shows range to a target, not including direction. The A-Scan plot is signal strength (amplitude volts) versus sampler (time or distance).

Salsa Scope with A Scan

Salsa Scope with B-Scan Display

The B-Scan plot displays signal strength (amplitude volts in gray-scale) versus range (meters) versus time (seconds), i.e. fast time versus slow time. Think of this as continuously stacked A-Scans.

Salsa Respiration Demonstration

The Respiration Demo provides the Respiration Waveform (top) as well as the instantaneous Respiration Rate (bottom), in breaths per minute (BPM).

Salsa Doppler Demonstration

Doppler demonstrates perturbations in the radar signal frequency caused by motion of the target, i.e. Doppler shift. Using Pulsed Doppler techniques inherently filters statics targets and accentuates moving targets.
