A coded long pulse is applied to the Jicamarca 50 MHz high power large aperture radar to study meteor head echoes. We develop a probabilistic detection model, which finds 25% more meteors than the commonly used signal‐to‐noise ...

Understanding the global meteor flux at Earth requires the measurement of meteor velocities. While several radar methods exist for measuring meteor velocity, they may be biased by plasma reflection mechanisms. This paper ...

We present here the first observations of a new type of meteor echo. These Low‐Altitude Trail Echoes (LATE), observed almost exclusively below 90 km altitude using the Jicamarca Research Observatory 50 MHz radar, exhibit ...

Millions of small but detectable meteors hit the Earth's atmosphere every second, creating trails of hot plasma that turbulently diffuse into the background atmosphere. For over 60 years, radars have detected meteor plasmas ...

We constructed a model of the plasma evolution of meteor trails in order to simulate high‐power‐large‐aperture radar observations. This model follows meteor evolution from ablation and ionization to head echo formation and ...

We present results of simulated radar observations of meteor trails in an effort to show how non-specular meteor trails are expected to vary as a function of a number of key atmospheric, ionospheric and meteoroid parameters. ...

We report the role that the ambiguity function (AF) plays on the determination of signal to noise ratio (SNR) collected from meteor head echoes. Theoretical analysis shows that any measured meteor SNR exhibits temporal ...
