Nyocha nke ụdị ngbanwe Laser: ụkpụrụ nka na ngwa nke koodu ugboro ugboro nkenke nkenke, Koodu etiti oge Pulse na-agbanwe agbanwe, yana koodu PCM.

Ka teknụzụ laser na-agbasawanye n'ọhịa dị ka nsonye, ​​nzikọrịta ozi, ịnyagharị, na nhụta anya, usoro mgbanwe na ntinye nke akara laser aghọwokwa iche iche na ọkaibe. Iji welie ikike mgbochi nnyonye anya, izi ezi dị iche iche, yana arụmọrụ nnyefe data, ndị injinia ewepụtala usoro ngbanwe dị iche iche, gụnyere Usoro Ntugharị Nkwugharị (PRF), Code Interval Variable Pulse, na Modulation Code Modulation (PCM).

Edemede a na-enye nyocha miri emi nke ụdị ngbanwe laser ndị a na-ahụkarị iji nyere gị aka ịghọta ụkpụrụ ọrụ ha, njirimara teknụzụ, na ọnọdụ ngwa.

1. Koodu ugboro ugboro nke ziri ezi (koodu PRF)

①Ụkpụrụ nka nka
Koodu PRF bụ usoro ngbanwe nke na-ebufe akara usu na ugboro ugboro ugboro ugboro (dịka, 10 kHz, 20 kHz). N'ime sistemu na-ahụ maka laser, a na-amata mkpụrụ akụ ọ bụla eweghachiri na-adabere n'ụdị ikuku ikuku ya, nke sistemụ na-achịkwa nke ọma.

②Atụmatụ igodo

Ọdịdị dị mfe na ọnụ ala mmejuputa iwu

Kwesịrị ekwesị maka nleba anya dị mkpụmkpụ na ebumnuche ntụgharị uche dị elu

Ọ dị mfe ịmekọrịta na sistemụ elekere eletrọnịkị ọdịnala

Na-adịchaghị irè na gburugburu mgbagwoju anya ma ọ bụ ọnọdụ ọtụtụ ebumnuche n'ihi ihe ize ndụ nke"multi-uru nkwughachi”nnyonye anya

③Ihe ngosi ngwa
Laser rangefinders, ngwaọrụ nha anya otu ebumnuche, sistemu nyocha ụlọ ọrụ

2. Koodu etiti oge Pulse na-agbanwe agbanwe ( Koodu nkeji oge ma ọ bụ nke na-agbanwe agbanwe)

①Ụkpụrụ nka nka
Usoro ngbanwe a na-achịkwa oge etiti oge n'etiti pulses laser ka ọ bụrụ ihe efu ma ọ bụ nke enweghị usoro (dịka ọmụmaatụ, na-eji ihe na-emepụta usoro pseudo-random), kama idozi ya. Ọdịiche a na-enyere aka ịmata ọdịiche dị na nloghachi ma belata ndabichi ọtụtụ ụzọ.

②Atụmatụ igodo

Ike mgbochi nnyonye anya siri ike, dị mma maka nchọpụta ebumnuche na gburugburu ebe mgbagwoju anya

Na-egbochi nkwughachi mmụọ nke ọma

Mgbagwoju anya ngbanwe dị elu, na-achọ ndị nrụpụta ike karịa

Kwesịrị ekwesị maka ọnụọgụ dị elu yana nchọpụta ọtụtụ ebumnuche

③Ihe ngosi ngwa
Sistemụ LiDAR, counter-UAV/Sistemụ nleba anya nchekwa, usoro laser agha na sistemụ njirimara ebumnuche

3. Mgbanwe koodu Pulse (koodu PCM)

①Ụkpụrụ nka nka
PCM bụ usoro ngbanwe dijitalụ ebe a na-atụpụta akara analọgụ, tụọ ọnụ ma tinye ya n'ụdị ọnụọgụ abụọ. Na sistemụ nkwukọrịta laser, enwere ike ibu data PCM site na pulses laser iji nweta nnyefe ozi.

②Atụmatụ igodo

Mgbasa kwụsiri ike na nguzogide mkpọtụ siri ike

Nwere ike ịnye ụdị ozi dị iche iche, gụnyere ọdịyo, iwu na data ọkwa

Chọrọ mmekọrịta elekere iji hụ na ngbanwe ziri ezi na nnata

Na-achọ modulators dị elu na demodulators

③Ihe ngosi ngwa
Ọnụ nkwurịta okwu Laser (dịka ọmụmaatụ, Sistemụ nkwurịta okwu Optical Space efu), njikwa anya laser maka ngwa agha/ụgbọ elu, nloghachi data na sistemụ telemetry laser.

4. Nkwubi okwu

Dị ka"ụbụrụ”nke sistemu laser, teknụzụ ngbanwe laser na-ekpebi ka esi ebufe ozi yana otu sistemụ si arụ ọrụ nke ọma. Site na koodu PRF bụ isi ruo ngbanwe PCM dị elu, nhọrọ na imewe atụmatụ ngbanwe abụrụla isi ihe na-eme ka arụmọrụ sistemu laser dịkwuo elu.

Ịhọrọ usoro ngbanwe kwesịrị ekwesị chọrọ nleba anya zuru oke nke ọnọdụ ngwa ahụ, ọkwa nnyonye anya, ọnụọgụ nke ebumnobi na oriri ike sistemụ. Dịka ọmụmaatụ, ọ bụrụ na ebumnuche bụ iwulite sistemu LiDAR maka ịmegharị ihe ngosi 3D mepere emepe, a na-ahọrọ koodu etiti oge pulse nwere ikike mgbochi siri ike. Maka ngwa nha anya dị mfe, koodu ugboro ugboro nwere ike zuo oke.
