3169公裡長的美墨邊界線，僅靠圍牆和人力巡邏來防止非法越境十分困難。
粗算一下，使用3100臺上海舶雲的近程定向警戒雷達，組成「雷達微波長城」，就可以做主動安防監控升級，全天候24小時「耳聽八方，眼觀四路」，隨時對可疑目標進行識別和預警，它不香嗎？
為此，小編特意寫了一封信投到了川普先生的「推特」：
Dear Mr. Trump,
This is Richard from a private Chinese company. I remember you promised to build a wall on the US-Mexico border and ask Mexico to pay for it when you were running for the president. As a foreign citizen, I don't judge whether this decision is right or wrong, but I want to provide you with a cost-effective alternative to bricks which could save 90% cost, because what you are doing right now doesn't looks very smart.
As a security company, I would like to provide you the product--"Directional Warning Radar", each radar radiation distance of 2 kms, to fully cover the us-mexico border, only need 2100 ones and nobody can escape the "Great Wall of radar". I do think it's a great idea as smart as you decide to build the wall. As for how let Mexico to pay it or further details, I am looking forward your reply if you are interested.
Regards,
Richard
言歸正傳，這款讓小編有叫板美墨邊境牆大工程勇氣的安防產品究竟為何方神聖？坐穩，我要發車了！
