METHOD REVIEW pulse-Doppler RADAR purposes against ground reflection

摘要

1. Overview The method of pulse-Doppler radar targets at the background reflections from the earth's surface, comprising the survey space and by forming the directional light in each angular resolution element search space coherent sounding pulse sequence to the total number of parcels and a repetition period which satisfy sufficiency conditions fast frequency radar selectivity for target detection and the uniqueness of the high-speed positioning detected targets aimed n Receiving during pauses operation of transmitter radar echoes purposes and interference reflections with subsequent time-frequency treatment by antijamming weighing frequency rejection of interfering reflections and the multichannel range and speed correlation and a filter processing the received echo signals, characterized in that before the space overview produce density measurement of range-velocity distribution multipath interference power, calculated velocity maloindeksnoy hyperbolic track wobble period Hovhan and duration of probing parcels, when forming the probing pulse parcels further wobbling period repetition and duration of pulse packages in accordance with the calculated hyperbolic law, and in the process of time-frequency processing of received echo signals are separated into a linearly frequency modulated partsialy, for each current controlled range related -skorostnogo resolution element search space evaluated to satisfy the condition not exceeding a predetermined energy threshold value
