Frank Lind
MIT Haystack Observatory
Dr. Frank D. Lind is a Research Engineer at MIT Haystack Observatory where he works to develop and use radio science instrumentation. At the Observatory he leads many technical efforts involving software radio instrumentation cutting across Geospace, Astronomy, and Space science. These instruments are used to make detailed physical measurements and have been part of many NSF, NASA, and DoD supported investigations. Key instrumentation includes the National Science Foundation’s Millstone Hill Geospace Radar Facility, the RAPID (Radio Array of Portable Interferometric Detectors) system, low cost array radars, software defined radio architectures for radio telescopes, and efforts to develop a space borne electromagnetic vector sensor for the upcoming NASA AERO (Aurora Emissions Radio Observer) and VISTA (Vector Interferometry Space Technology using AERO) cubesat missions. Dr. Lind studied at the University of Washington where he received a Bachelor of Science degree in Physics and a Bachelor of Science degree in Computer Science in 1994. He then joined the UW Geophysics Program and pursued studies leading to the Doctor of Philosophy in Geophysics in 1999. His work there focused on Passive Radar observations of the Aurora Borealis. He is a prior chair of USNC URSI Commission G (United States National Committee of the International Union of Radio Science), a member of the American Geophysical Union (AGU), and a member of the IEEE.

Excellent lecture on a topic I'm most interested in. The very knowledgeable Dr. Lind made the hour + 23 minutes go by rather quickly. A lot of information to process. I did note quite a few topics to follow up on in order to solidify my understanding. I'm compelled to listen to his other session on radar. Making the slides available would be helpful, but I did save screen shots for me to reference.

The most important point of this presentation "(SDRs) These are going to get smaller. Everything is going to disappear into the antenna eventually...". Mind goes: "BOOM!!!" Thank you MIT & Dr. Frank D. Lind for this valuable presentation!

Just a suggestion. I’d put the slides in the main part of the screen and place a very small instance (if at all) video feed of the hall in the corner.

Another great presentation. Thank you! Request: Please use a mouse to highlight aspects of the presentations. The KZfaq medium is blocking 100% of the laser pointer's energy :)

Would love to see a practical sdr course, that first goes over the applications and uses of SDR. Things like.. Morse Code CW Transmission (NFM and AM/USB) and decoding/Receiving (CW Skimmer, CWGet , morsecode scphillips translator, etc) HAM : trunking (SDRTrunk / Unitrunker) / TETRA (SDRsharp plugin, OpenEar, OsmocomTETRA), digital-modes (DMR, D-Star, System Fusion/C4FM, NXDN, P25/Police Scanner (DSD LouisErigHere), POCSAG (PDW Software) , YSF FT8 )) , convert modes on the fly (i..e use DMR radio to talk on C4FM), Decoding/Visualizing Weather Satellite data (noaa-apt, WXtoImg ) ADSB Plane Tracking (X-Plane / XHSI and AdsbSCOPE plugin, MultiPSK with Maperitive) GPS Decoding/Plotting/Spoofing ( GNSS-SDRLIB, RTK-NAVI) ATSC Video Receiver/Transmitter (Portsdown DATV, SDRAngel, GRC, SDRGlut) Local GSM/LTE cellular network (GPRS) (gr-gsm, Kalibrate, IMSI-catcher, srsLTE-Sniffer, rtl-sdr-LTE dedsecimsi, FALCON) Text/voice decoding (OpenEar, Defcon 2016) Inmarsat AERO satellite Medlink AMBE Audio ACARS (jontio / libaeroambe built JAERO) Reverse Engineer an RF keyfob ( clock-recovery, analyze protocol (Universal-Radio-Hacker, Inspectrum), transmit ) Reverse Engineer Direct Sequence Spread Spectrum For example, anyone know if these SDR courses cover the above : Great-Scott HackRF Course, scannerschool teachable , $2500 Sébastien Dudek , $1500 hackers-arise Subscriber-PRO SDR For Hackers, Balint Seeber / Ettus Research GNU Radio Tutorials , tonex , commtech-academy , enoinstitute , zoetalentsolutions , sectrain hitb 2021SIN , Georgia Tech Prof. Edu, $15 Udemy (Designing RF Comm Systems using SDRs with GNU Radio, Mastering SDR with GRC, etc), factorialabs , csun skatz CSUN/EAFB Software Defined Radio (SDR) Senior Project, ECE4305?

It sucks that the slides stay up in the upper right corner; too hard to read, even when on full screen mode. Most decent lecture streams devote the whole window to the overheads because we don't need to continually see the lecturer standing there talking.

With large distributed arrays of receiver stations generating huge volumes of data I can't help thinking we need to develop more robust storage systems. Using SSD data storage units must carry a high level of risk with current SSD units having such short working lifetimes and high failure rates.

Hi this is a great series . So much knowledge. However, this guy seems to be claiming lots of firsts from closed projects . If it wasn't published it lacks proof it was done.

Well, you do know that it wasn't marconi who did it, but it was actually Nikola Tesla?! Marconi, just tookj tesla's work and took credit for it. Marconi was kind of a fraud, regarding the radio invetnion
