Over-the-horizon radar and its air defence application;

Design of transmitting waveforms and its demodulation in the coast-ship multi-static ground wave over-the-horizon radar;

An approach to suppressing meteor trails interference in the over-the-horizon radar;

In the HF ground wave OTH radar,the movement of the radar brings about the spreading of the first order Bragg lines.

An algorithm of weighting in the horizontal polarized channel is proposed which is effective to reduce the polarization mismatch loss and to improve the interference suppression ability of polarization filter in HF ground wave OTH radar.

For HF ground wave OTH radar to detect ship targets in the shipboard environment is faced with a range of technical challenges.

Summarization of Computer Network Technology in OTHR′s Application;

Research of Skywave OTHR Target Extraction;

Over-the-horizon radar(OTHR) which operates in a high frequency (3-30MHz) band can detect and track moving targets beyond the horizon such as vessels on sea and aircrafts at low altitude,it plays important role in military and civil applications.

More and more countries pay great attention to HF(high frequency) ground wave OTHR (over the horizon radar) for its military and civil foregrounds.

Method for maneuvering target detection in HF over-the-horizon radar;

It is high loss of rate in over-the-horizon radar on the condition of low detection probability.

A model for evaluating sky wave over-the-horizon radar combat efficiency;

According to the structure and task of sky wave over-the-horizon radar, the author used ADC evaluation model modeling with usability vector A~t, creditability matrix [D], power vector C and anti-jamming gene K_(AJ).

According to the characteristics and basic tasks of sky wave over-the-horizon radar,based on the method of Analytic Hierarchy Process(AHP), the hierarchy structure of the operational effectiveness evaluation index of sky wave over-the-horizon radar is set up.
