## Summary

Raised $150M Series B (Nov 2025) from Lockheed Martin, Capricorn Investment Group, VXI Capital. $175M total. Summit sensor unveiled at CES 2026. 5 top automakers engaged. All-weather terahertz sensing.

## Company Overview

Teradar is developing Summit — a terahertz-band vision sensor that combines the high-resolution imaging of LiDAR with the weather-penetrating capability of radar, addressing the fundamental limitation that has blocked autonomous vehicle deployment in rain, snow, and fog. The company raised $150 million in Series B financing in November 2025 from Lockheed Martin Ventures, Capricorn Investment Group, and VXI Capital (a defense-focused fund with former DARPA/DIU executives), bringing total funding to $175 million. The Summit sensor was unveiled at CES 2026 with five top automakers engaged in evaluation programs.

The physics of sensing creates a fundamental tradeoff in existing sensor technologies: LiDAR provides centimeter-level resolution but scatters in precipitation; radar penetrates weather but has centimeter-level resolution only at close range. Terahertz frequencies (300 GHz to 3 THz) occupy the electromagnetic spectrum between the two — offering both weather penetration and high resolution in a single sensor that neither LiDAR nor radar can achieve independently.

Lockheed Martin's investment signals the dual-use (automotive + defense) commercial strategy: the same weather-penetrating high-resolution sensing that enables autonomous vehicles in blizzards also enables defense platforms to detect and classify objects through smoke, dust, and electronic countermeasures. This dual-use positioning gives Teradar government contract revenue that subsidizes automotive R&D — a financing structure that defense-backed sensing startups uniquely benefit from.

## Frequently Asked Questions

### What does Teradar make?
Summit — a terahertz-band vision sensor combining LiDAR-resolution imaging with radar-like weather penetration. Solves the fundamental all-weather limitation that prevents autonomous vehicle deployment in precipitation.

### How much has Teradar raised?
$175M total including $150M Series B from Lockheed Martin, Capricorn Investment Group, and VXI Capital. Summit unveiled at CES 2026, 5 automakers engaged.

### Why is terahertz sensing better than LiDAR or radar?
LiDAR scatters in rain/snow; radar lacks resolution. Terahertz frequencies (between them) offer both weather penetration AND centimeter-level resolution — a capability neither existing technology achieves.

### Why does Lockheed Martin invest?
Terahertz sensing has dual-use: same capability enabling autonomous vehicles in blizzards also enables defense platforms to detect through smoke, dust, and countermeasures — government contracts subsidize automotive R&D.

### How does terahertz sensing work and what makes Teradar's approach novel?
Terahertz (THz) waves (frequencies between microwave and infrared, ~0.1-10 THz) penetrate clothing, packaging, and most non-metallic materials while providing millimeter-scale resolution — similar to radar penetration but with much finer resolution than conventional radar. Teradar's chip-scale THz imaging achieves this in a compact semiconductor package rather than the room-sized lab equipment previously required, enabling vehicle-mounted and drone-mounted deployment.

### What autonomous vehicle problem does Teradar solve?
LiDAR fails in rain, fog, snow, and bright sunlight — common real-world conditions. Radar works in adverse weather but lacks the resolution to identify pedestrians, cyclists, and road debris reliably. Teradar's THz sensors fill the gap — adverse weather penetration with resolution approaching LiDAR quality — providing a critical sensing modality for Level 4/5 autonomous vehicles that need all-weather capability without sacrificing object discrimination fidelity.

### What is the Lockheed Martin investment significance?
Lockheed Martin's strategic investment validates Teradar's technology for defense applications — through-wall imaging (identifying people in buildings without line-of-sight), personnel screening, and drone/vehicle detection in contested environments. Defense contracts typically provide substantial early revenue and technical validation that accelerates automotive customer qualification, since defense procurement demands higher reliability standards than automotive qualification processes.

### How close is Teradar's technology to automotive production integration?
Teradar is in the development and customer evaluation phase, working with automotive OEMs and Tier 1 suppliers to demonstrate THz sensor performance in prototype vehicles. Automotive sensor qualification (IATF 16949, AEC-Q100 reliability standards) typically takes 3-5 years from initial evaluation to production SOP (start of production). Teradar's 2024 funding positions it for accelerated qualification programs targeting 2027-2029 automotive model year integration.
